I migrated from Twitter to Mastodon when Elon Musk took over. It’s been really nice, and I I wish I’d have known about the Fediverse before then. I may have found an instance that is too comfy and perfect for me, though… I’ve been tempted to migrate my account over to a Calckey instance, but there’s no way that I’m not staying put. Other Fedi services that I’m interested in trying are PeerTube and Owncast.
I joined Mastodon at the same time you did, and have taken to it as much as I ever did Twitter. That is to say, I waste far too much time shitposting on there.
I tried to set up a PeerTube account on one of the bigger instances (I forget which), but my account was never approved and I forgot all about it.
