I hate that the conversation online has moved from distributed to federated, I understand that running p2p software is harder for the user, but I feel like actually distributed microblogging / social networks are the right choice going forwards.
p2p stuff looks like it's getting better
there's iroh, which looks like a nice balance of batteries included, and not a bunch of bloat
and pkarr, which does exactly one thing: maps ed25519 keys to DNS records via bittorrent's DHT
i think the big blocker for wider adoption is that browsers, ISPs, and airport wifi are all hostile to general purpose network protocols. you're mostly stuck with TCP, or the quagmire of WebRTC right now. (iroh works in the browser, but it has to go through a relay)
Not even microblogging, jut blogging in general. ActivityPub could be a replacement for RSS readers. I consider a platform that allows you to mix microblogs, blogs, podcasts, videos, and livestreams/events the "endgame" - all of which can be done with ActivityPub (albeit with different projects today). Unfortunately this is not the type of project that I would find interesting at all to write.
