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’ve been on Mastodon on and off over the years. Mainly just use it to lurk. Been trying to get into Peertube, but the lack of quality content (for topics I’m interested in at least) has made it difficult. Hopefully that will change as the Fediverse really begins to take off.
