> Do you have a more pointed criticism?

Sure.

After taking the time to re-read the article since I initial posted my (admittedly shallow) dismissal, I realized this article is really a primer/explainer for the AT protocol, which I don't really have enough background in to criticize.

My criticism is more about the usefulness of saying "what if we treated social networking as a filesystem": which is that this doesn't actually solve any problems or add any value. The idea of modeling a useful thing (social media)[0] as a filesystem is generalizing the not-useful parts of it (ie. the minutia of how you actually read/write to it) and not actually addressing any of the interesting or difficult parts of it (how you come up with relevant things to look at, whether a "feed" should be a list of people you follow or suggestions from an algorithm, how you deal with bad actors, sock puppets, the list goes on forever.)

This is relevant to Joel's blog because of the point he makes about Napster: It was never about the "peer to peer" or "sharing", that was the least interesting part. The useful thing about Napster was that you could type in a song and download it. It would have been popular if it wasn't peer to peer, so long as you could still get any music you wanted for free.

Modeling social media as a filesystem, or constructing a data model about how to link things together, and hypergeneralizing all the way to "here's how to model any graph of data on the filesystem!" is basically a "huh, that's neat" little tech demo but doesn't actually solve anything. Yes, you can take any graph-like structured data and treat it as files and folders. I can write a FUSE filesystem to browse HN. I can spend the 20 minutes noodling on how the schema should work, what a "symlink" should represent, etc... but at the end of the day, you've just taken data and changed how it's presented.

There's no reason for the filesystem to be the "blessed" metaphor here. Why not a SQL database? You can `SELECT * FROM posts WHERE like_count > 100`, how neat! Or how about a git repo? You can represent posts as commits, and each person's timeline as a branch, and ooh then you could cherry-pick to retweet!

These kind of exercises basically just turn into nerd-sniping: You think of a clever "what if we treated X as Y" abstraction, then before you really stop to think "what problem does that actually solve", you get sucked into thinking about various implementation details and how it to model things.

The AT protocol may be well-designed, it may not be, but my point is more that it's not protocols that we're lacking. It's a lack of trust, lack of protection from bad actors, financial incentives that actively harm the experience for users, and the negative effects on what social media does to people. Nobody's really solved any of this: Not ActivityPub, not Mastadon, not BlueSky, not anyone. Creating a protocol that generalizes all of social media so that you can now treat it all homogeneously is "neat", but it doesn't solve anything that you couldn't solve via a simple (for example) web browser extension that aggregated the data in the same way for you. Or bespoke data transformations between social media sites to allow for federation/replication. You can just write some code to read from site A and represent it in site B (assuming sites A and B are willing.) Creating a protocol for this? Meh, it's not a terrible idea but it's also not interesting.
