Thoughts on Fleets

Twitter launched their version of Stories last week (called Fleets) – some initial thoughts:

  • I think the Stories format fits Twitter better than any other social network because it’s actually quite similar to how Tweets work. Both Stories and Tweets are modularized content. They work as stand-alone micro content (Tweet / Fleet) or can be grouped into a bigger piece of content (Tweet storm / Story) with sub-discussions for each element.
  • The difference between the two formats is that Tweet discussions are public whereas Fleets will drive more usage of private discussions via Twitter DMs. This is a good thing. Twitter DMs are the most underrated part of the site (and probably the best shot any company has at disrupting LinkedIn). I just wish Twitter had improved DMs before driving more users to it.
  • When Instagram launched Stories, it saw that users posted less to the newsfeed – which they reserved for their best / most important photos. I wonder if we’ll see a similar trend on Twitter, but I doubt it. Tweeting photos and videos was never a great user experience, mainly because of the weird way Twitter auto-crops them, so I don’t think we’ll see cannibalization between the two formats.
  • The animation when swiping between Fleets feels clunky. Instagram Stories feel 10x smoother.
  • The creator tools for Fleets are by far the biggest disappointment. Twitter had a real chance to build something new here (personally, I think audio would be a *really* interesting format). Instead, it’s just a very limited version of other Stories features.
  • The Stories bar is great UI real estate for other features: I really hope Periscope will make a comeback. The rumored audio rooms would also fit nicely here.

Chief Notion Officer

I’ve been thinking a lot about corporate knowledge management systems recently.

If we think about a company as an organism, then a knowledge management system is essentially the (collective) brain that keeps that organism alive and running. A corporate knowledge management system should contain every single bit of codifiable information within the company resulting in a library of all projects, processes and procedures.

In an ideal state, it is the single source of truth that helps to inform every individual in the firm about what everyone else is up to. Information should be easy to add (input) as well as easy to search and find (output) resulting in quick knowledge transfer between different employees.

In reality, however, this hardly ever is the case. As anyone who has ever worked at a larger company can attest to, company knowledge bases always end up being a huge mess.

What starts with a neatly organized Confluence wiki, over time morphs into a multi-headed monster consisting of millions of notes and documents that live across Google Docs, Dropbox Paper, Asana and half a dozen different wiki tools. Most docs will be outdated, some will contradict others and the one you are really looking for only shows up on page 14 of your search results.

It seems like things usually start to fall apart once a company surpasses the Dunbar number of 150 employees. This is probably when people start to realize that all the different documents of explicit knowledge they were amassing over the years have been held together with implicit knowledge.

It’s easy to find – and understand – the right documents when you know every other person in the company, but once you’re past that point, you need a system to organize all the data so that people can make sense of it.

The idea behind tools like Notion is to solve this problem by using just one tool for all your different knowledge documents. Instead of Google Docs AND Asana AND Trello AND Airtable, you just do everything in Notion. This reduces complexity because you don’t have to switch and search across different apps. At the same time, Notion forces you to think about a system that makes information easy to find with its folder-like structure and links between different databases.

I’ve never used Notion with more than half a dozen people myself, but from what I’ve heard from people at larger companies, Notion knowledge bases also don’t scale very well beyond a certain number of users. Once too many people start contributing to it, things become bloated and unnavigable.

A friend at Stripe recently suggested – half-jokingly – that we should hire a librarian to organize all our internal data and documentation. The more I think about it, the more I like the idea. Perhaps every company should hire a Chief Notion Officer once it hits 100 employees?!

An alternative approach to Notion is a knowledge management system that can live across different tools and without active manual curation because it’s based on really powerful search. The folder structure of your Google Drive, for example, doesn’t really matter because looking up documents via search is faster and more convenient. Meta search tools like FYI are supposed to offer the same but across different productivity tools.

But again I’m skeptical that this really works beyond a certain amount of users (and thus documents). I remember even Google’s internal search engine doing only a mediocre job of surfacing the most relevant documents (and even if it did you weren’t sure if there wasn’t a better or more up-to-date version of it).

I’m sure we’ll get there eventually, but until then we probably need a mix of automated search and manual human help – which is where Slack comes in. I’ve always thought Slack plus Notion plus Spoke would make a really powerful product (and I’m surprised Slack hasn’t made any major acquisitions in this space).

If you think about it, Slack is basically a search engine powered by humans: Most Slack messages are just questions. It’s 911 for when everything else fails. So if Slack had access to your entire knowledge base, it could answer at least the most commonly asked questions automatically. The rest would still get answered manually by the channel participants. Or your Chief Notion Officer.

Do you have thoughts on this topic? Please leave your feedback here.

Inventory Update (Q4/20)

This is a quarterly update and review of new tools and products I have recently added to my personal productivity stack.

+ Added to Inventory
  • Autonomous SmartDesk 2
    It looks like we’ll all have to work from home a little while longer, so I finally decided to invest in a proper home office setup. After some Twitter research, I eventually settled on the Autonomous SmartDesk2. Pretty happy with it so far.
  • Autonomous ErgoChair 2
    Related to the above. The chair is great, but I hate that I can’t fit the armrests under the desk – is there an ergonomic reason for this or just poor design?
  • Comandante C40 MK3
    Upgraded my coffee stack (which has a major impact on my productivity) with a Comandate C40 grinder, which not only looks and feels fantastic but also gives me a way more consistent grind size than my old Hario. Recommended.
Removed from Inventory
  • Superhuman
    This wasn’t an easy decision. As I pointed out before, Superhuman is *by far* the best email client ever built – and it will only get better as they add more integrations with other tools. Superhuman would save me at least 30 min per day at work … the problem is, I can’t actually use it at work (security reasons). This has made a little difficult for me to justify the $30 price tag.
? Testing
  • I’ve been playing around with different audio-first social apps in the last couple of months. Clubhouse has been particularly fun (don’t believe everything you read about it on Twitter); Sonar also has a couple very interesting ideas.
  • I’m experimenting with different widgets in iOS 14. If you have any recommendations, please let me know.

A Meta-Layer for Notes

What’s the digital equivalent of sticky notes?

01 Hey

This was originally supposed to be a blog post about Hey. I wanted to write a longer essay about Basecamp’s new email tool and test if the app actually lives up to its hype.

After playing around with it for a few weeks, my conclusion is this: Hey’s most interesting aspect is not its radical approach to email – but its fresh approach to note taking!

We have long treated notes as a distinct silo in our productivity stack, when we should have integrated them right into our workflows instead. While email might need an overhaul, I see a way bigger opportunity in rethinking digital note taking.

So instead of my Hey review, let’s talk about notes and my idea for a radically new kind of note taking app.

02 A Closer Look at Notes in Hey

Hey has two interesting notes features.

The first are so-called Thread Notes. These are basically emails to yourself within an email thread that only you can see. You might have seen similar internal notes features in shared inbox tools like Zendesk or Front. Thread Notes in Hey are effectively the single player version of those.

I’d find Thread Notes super useful in combination with snoozed emails: “Show me this email again in [insert time] and remind me of [insert note]”

This feels like a way better workflow than adding a note in a separate reminder, to-do, CRM, or note taking app.

a) Because there’s no need for context/app switching.
b) You might not even remember that you took a note related to an email when it resurfaces in your inbox a few weeks later.

To-do and reminder apps (and calendars!) work great for tasks that are tied to a specific day or time. But many tasks – and especially notes – are not dependent on time. Their relevance is based on other trigger points. Only when certain conditions are met, should these notes resurface: “If [insert event] is true, then show [note]”

In the case of our email, the note becomes relevant in [insert snooze time] or whenever the recipient replies to the email thread. The fact that many tasks have external dependencies (which are usually linked to an email thread) is one of the reasons I believe that your email inbox should also be the place where you manage your to-dos. You shouldn’t need a separate to-do app.



The second note feature in Hey are Inbox Notes.

As the name suggests, these notes are added to individual emails in your inbox. Similar to Thread Notes, you can use them to quickly jot down things you need to remember, but they also help you to highlight specific emails.

Thread Notes and Inbox Notes feel similar, but they serve two slightly different use cases. Thread Notes work more like reminders (“Don’t forget X when you reply”), whereas Inbox Notes feel more like bookmarks that highlight the most important messages in a long list of emails.

Together, they remind me of one of my all-time favorite note taking tools: Post-it Notes.

03 Post-it Notes

I’m a huge fan of physical note taking and there are two writing tools that I use every single day: A physical notebook (for longer thoughts, including first drafts of my blog posts) and post-it notes (for all kinds of quick notes).

(Disclaimer: When I say “post-it notes” I’m referring to all types of sticky notes, not just those sold by 3M.)

Post-it notes serve two of the same functions that Hey’s note features offer: highlights and reminders.

One of the reasons I still read a lot of non-fiction in physical book form is because it’s easier to bookmark and annotate passages that I quickly want to find again later. Similar to Thread Notes, sticky note bookmarks help me highlight the most important items in a long list.

Apart from helping you find important passages in a book later on, sticky note bookmarks also allow you to add additional context to the section you highlighted (e.g. *why* you bookmarked a particular section or thoughts you had about it).

You could write down notes like this in a separate notebook, but then you’d lose the connection to the source they are based on. What makes post-it notes so interesting is the spatial relationship between the notes and their respective context.

It’s this spatial relationship that also make post-it notes great reminders.

Post-it note reminders are similar to Hey’s Thread Notes in that they are triggered not based on time but on events that don’t have a (forecastable) deadline. They are essentially like notifications that appear when you look at specific objects.

A post-it note on your front door, for example, is like a notification that pops up when you’re about to leave the house: “Before you go, don’t forget to [insert note]”. A shopping list on your fridge is a data request notification that surfaces when you are most likely to have new items to add to your list.

Together, post-its essentially become a notes layer that augments the real world. Instead of a physical notebook that lists all your notes and tasks in chronological order, post-it notes are scattered around your house but tied to specific places or objects where they are most relevant.

The question is: Why isn’t there a digital note taking tool that works like this?

04 A Spatial Note Taking Layer

There are dozens of great note taking apps out there: Evernote, Google Keep, Apple Notes, Workflowy, Notion, Roam … the list goes on and on. Every one of these tools has its own unique angle on note taking, but they all have one thing in common: They are stand-alone apps.

This strikes me as suboptimal. Neither the creation nor the consumption of notes should be treated as separate workflows.

As John Palmer points out in his brilliant posts on Spatial Interfaces and Spatial Software, “Humans are spatial creatures [who] experience most of life in relation to space”. Post-it notes are so powerful because they have a spatial relationship to their context.

Many notes shouldn’t live in a dedicated note taking app that you explicitly have to open and search. Notes should emerge automatically whenever and *wherever* they are most relevant.

As long as note taking remains separated, users constantly have to switch back and forth between different applications, which is not ideal. It reminds me of the recent discussion around productivity and collaboration – which have historically also been treated as two separate, isolated workflows:

The platonic flow of productivity should minimize time spent not productive, with collaboration as aligned and unblocking with that flow as possible. By definition, any app that requires you to switch out of your productivity app to collaborate is blocking and cannot be maximally aligned. It’s fine to leave your productivity app for exceptions and breaks. But not ideal when working.

The same applies to notes. You shouldn’t have to switch apps and context to take or consume notes. It should stay within the same workflow!

(Side Note: You could argue that note taking is essentially single-player collaboration where you communicate with your future self – but that’s a whole new discussion I’ll save for another blog post.)

Natively built in note taking features like email notes in Hey feel like a good step in the right direction – but email is just one distinct silo in your productivity stack. Imagine you had to buy different sets of post-it notes for every single room or object in your house.

What we need instead is a spatial meta layer for notes on the OS-level that lives across all apps and workflows. This would allow you to instantly take notes without having to switch context. Even better yet, the notes would automatically resurface whenever you revisit the digital location you left them at.

Let’s look at a few examples.

05 Examples

One use case that immediately came to mind when I thought about spatial notes is bookmarking.

Most of us don’t use just one bookmarking app for everything. We use different bookmarking apps or bookmarking features depending on the type of object we want to save for later: Podcasts are usually saved in a dedicated podcast app, for example. Articles are bookmarked in Pocket, books on Goodreads, songs on Spotify, places on Foursquare, products on Amazon … you get my point.

Bookmarks are great to remember *what* you want to revisit later – but not *why* you saved something in the first place. I would love to be able to add notes to my bookmarks directly in each app so that I have some context on why these objects are important when I return to them later.

Ideally, these notes wouldn’t just show up in the one place I originally left them, but across all apps and websites that reference the (semantic) object I bookmarked. A note attached to a book I want to read in Goodreads, for example, should also emerge when I see that book in my Amazon search results – or when someone mentions it in my Twitter timeline.

People are a similar type of semantic object you could tie notes to. Instead of a stand-alone CRM tool, you would leave a note attached to a person straight from your current workflow (e.g. your email client). That note would then automatically re-surface whenever the person it references becomes relevant again:

  • When you’re in an email thread with them
  • When you add them to a calendar event
  • When you’re visiting their LinkedIn page
  • When you look them up in your phone book
  • etc


Another use case for spatial notes are instructions on how to use specific software features or improve workflows. These could be quick reminders to add permissions to new calendar events or to use Filtered Views in Google Sheets. You could also use these notes to train users on keyboard shortcuts.

You could imagine employers shipping corporate laptops with pre-installed notes to make it easier to transfer (previously tacit) knowledge and thus improve the onboarding process for new hires.

06 Closing Notes

I could go on and on about potential use cases for a spatial note taking app. The possibilities are endless – but blog posts shouldn’t be. So I’ll end things here.

A final note before you leave: I’d love to hear your thoughts on this whole idea. What would you use a spatial note taking tool for? Let me know what you think in this Twitter thread!

Proof of X

01 Intro

Sparked by an interesting Twitter discussion, I’ve spent a lot of time recently thinking about different proof-of-work mechanisms.

When I say proof-of-work, I’m not talking about consensus algorithms like the ones that some crypto currencies use. I’m talking about social networks.

At their core, social networks are primarily about one thing: Building social capital through signaling. As I wrote in Signaling as a Service, signaling can be broken down into three different components:

  • Signaling Message
    A hidden status subtext you’re trying to convey about yourself
  • Signaling Distribution
    The channel through which you’re communicating your signaling message
  • Signaling Amplification
    Ways to boost your signaling message to compete against status rivals

For example: A Patagonia vest signals both a prosocial attitude (“I care about the environment“) as well as wealth (“I can afford to spend $500 on a jacket“). Depending on where you live, it might also signal something about your occupation.

In order to signal these messages to others and build actual social capital you need a signaling distribution channel. One option would be to wear the vest in public where others can see it – but there are obvious physical constraints to the size of the audience you’d be able to reach.

This is where social networks come in.

Their primary role is to distribute signaling messages at scale and transform them into quantifiable social capital (in the form of likes and followers).

As social networks grow, they increase the potential reach of your signaling messages – but they also get crowded with status rivals. This is why social networks typically provide you with a set of signaling amplification tools. These tools help you boost your signaling messages and stand out from the crowd.

In Signaling as a Service I compared signaling amplification to Eugene Wei’s idea of proof-of-work hurdles, which he describes as follows:

Almost every social network of note had an early signature proof of work hurdle. For Facebook it was posting some witty text-based status update. For Instagram, it was posting an interesting square photo. For Vine, an entertaining 6-second video. For Twitter, it was writing an amusing bit of text of 140 characters or fewer. Pinterest? Pinning a compelling photo. You can likely derive the proof of work for other networks like Quora and Reddit and Twitch and so on. Successful social networks don’t pose trick questions at the start, it’s usually clear what they want from you.

But the more I think about it, the less I like the comparison. I actually think that Eugene’s proof-of-work theory only scratches the surface of what social networks actually do.

Let me explain.

02 A closer look at proof mechanisms

Take a look at this very cliché Instagram picture. The photographer clearly put a lot of thought and effort into its composition and applied different filters and editing tools to make it look nicer.

Full disclosure: I actually took this picture from Unsplash. No influencers were harmed during the production of this blog post.

It’s a perfect example of Eugene’s definition of proof-of-work.
Proof-of-creative-work, to be more exact.

Editing your photo helps to amplify your signaling message and sets you apart within Instagram’s status arena (aka the newsfeed). It also adds additional signaling messages to your post: “Look how great a photographer I am” or “I’m a creative person”.

But those are not the main signaling messages you are communicating here. What you really want to tell your followers with this photo is something along the lines of “I’m a world-traveler” and “I’m in a happy relationship” (which in turn are also just signaling proxies for wealth and mating worthiness).

The photo and the location tag are your proof points.

If you look closely, you’ll notice additional hidden signaling messages in the form of Allbirds sneakers and what’s most likely a Patagonia vest → proof-of-ownership

Social networks are therefore not only signaling distribution (and amplification) networks – they also allow users to prove their signaling messages.

The creative proof-of-work is just pretext and helps to boost your post. What’s more important are the additional proof mechanisms that social networks provide. In the case of Instagram those are photos and location tags.

Instagram is essentially “pics or it didn’t happen”-as-a-service.

03 Implications for new social networks

When new social networks emerge they have to introduce new proof mechanisms to differentiate themselves from existing incumbents. These can either be novel proof-of-creative-work hurdles or completely new proof-of-x mechanisms.

TikTok is a good example for proof-of-creative-work innovation. The app provides creators with a powerful set of video editing tools that have opened a whole new level of creativity.

The cost to participate in TikTok’s status game is a lot higher than Instagram’s (compare a well-made dance choreography on TikTok to your median Instagram travel post) – but its powerful feed algorithms also make discovery easier and thus reward users faster and with more social capital.

TikTok doesn’t add any new proof points beyond its novel creative work hurdle though. You can signal and prove your creativity but you could achieve the same by uploading your video to Instagram.

Strava, on the other hand, introduced an entirely new proof mechanism: Proof-of-physical-activity. By using your phone’s GPS sensor (or a 3rd-party fitness tracker), users can actually prove how much and fast they ran or cycled. In contrast to Instagram photos, Strava’s proof mechanism is a lot harder to fake (though there are exceptions).

What’s great about Strava is that it reinforces a behavior that’s actually good for you: While the status game that initially got you into the app might be zero sum, the actual physical exercise you have to put in to compete has a very positive, compounding effect.

The question is: What other social networks should we build that could have similar positive feedback loops? And what are their proof mechanisms?

04 Strava for X

Let’s start with the two examples in this tweet.

I love the idea of a Strava for Cooking – but I’m very skeptical that it can be built. Why? Because the necessary proof mechanisms don’t exist.

The primary metric you optimize on when cooking is taste. But how would you measure or quantify taste? The closest proxy to taste that we have is optics: How good does the meal that you cooked look? This can easily be proved with a photo .. but that’s a proof-of-work mechanism that Instagram already offers (including filters to make your food look nicer). As long as no one comes up with a better proof mechanism for cooking, I think it’s unlikely that we will see a successful social network in the space.

I’m more optimistic about Strava for Learning.

While the activity of learning itself might be hard to quantify, you can measure the outcome of learning: knowledge. Has anyone built a multiplayer version of Anki yet? Flash cards would be a perfect proof-of-knowledge mechanism and could easily be turned into a game where you compete against friends.

Similar to physical activity in the Strava example, learning is not something that most people enjoy doing. As TikTok founder Alex Zhu points out, education goes a little against human nature. In combination with a strong enough signaling mechanism however, you can get users to participate. It’s kind of the opposite of Chris Dixon’s famous “Come for the tool, stay for the network” strategy. Come for the status, stay for the tool.

A related product I’d love to see is Strava for Reading. Imagine an eBook reader that not only tracks how much time you spend reading but also *what* you are reading. Based on these proof-of-(reading)-work mechanisms you could build streaks or GitHub-contributions-like visualizations that incentivize users to read more (and more regularly).

You could even build leaderboards for different topics based on the content of the books and articles you read. Or think about a score that indicated how balanced your reading behavior per topic was (to incentivize users to read takes on political topics from different perspectives).

Unfortunately, I think it’s unlikely that we will see a product like I described anytime soon. The world’s largest bookstore, most popular eBook reader, and biggest social network for books are all owned by a company that has very little competency in design and user-facing product innovation.

(Side note: Amazon’s monopoly on books might be the most underrated sub-optimal equilibrium in tech.)

Another app that would be interesting is a social investing app. Think “Robinhood but as a social network”. It seems like investing is already quite a social activity – just look at communities like r/wallstreetbets. As patio11 pointed out, Robinhood already feels more like a game than a finance app.

So why not build an investing app that opens with a feed of all your friends’ investments and their returns over time? Instead of sharing screenshots on Reddit and Instagram you could prove your investments right in the app.

Note that an app like this would not be about signaling wealth. It’s about signaling being right and the ability to prove it. This is probably an even stronger and more engaging mechanism than signaling wealth – and the reason why I’m still bullish on prediction markets.

Perhaps a well-designed, consumer-friendly prediction market app would be the ultimate proof-of-x social network. Strava for being right.
