If you like Mastodon, I'd recommend checking out SSB. It's completely peer-to-peer, you own your own data, you host the data of people you follow, and it's one of the best communities I've ever been a part of. Plus we have other sub-protocols like secret sharding for social password management and chess and other fun stuff. Super neat, I can't recommend it enough.
