Nostr (https://nostr.com/) is doing reasonably- though I think most apps are still in the social media realm.

Not judging technically, but there are reasons I wouldn't touch it with a 10 meters pole.

Hyphanet is great but requires some basic skills and hardware for running. Using Nostr with Primal as a client works exceptionally well as a Twitter alternative. It's privacy-respecting, censorship-resistant, and truly an outstanding tool. I'm grateful it exists to counter the current wave of regulatory overreach threatening free speech, even in Western countries.
