Nostr is super flexible too since its a protocol. I see reddit-style and hacker news style sites, documentation sites, blog sites...and yes twitter/x style sites as well.

Hell there's even a streaming platform on nostr too. The common criticism is that its all bitcoiners, that's mainly because it uses Lightning Network for zaps and that's how people get paid in nostr. So naturally its a lot of bitcoiners in the nostr communities.
