It doesn’t work for everything though. Having a self hosted account that wasn’t tied to any specific platform or instance would ideally allow you to have access to PeerTube and BookWyrm as well as Mastodon and Kbin, without having to worry about your instance shuttering and all of your posts and comments disappearing. I’ve also been really stewing on this idea, I think it’s a probable future state of the Fediverse
Most of my friends jumped off Reddit and onto Kbin/Lemmy for the week of the blackout. I think most of them are using some hybrid of Lemmy/Reddit now. I’m the only person I know that moved exclusively to Kbin, but that’s okay. It fills the same hole that reddit did, I don’t much care if other people I know do or do not join tbh
