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 do have one on kbin, but I don’t use it. I think the kbin interface is way better than Lemmy, but I dig the vibe over here more. No shade to anyone, they are both great. Just personal preference.
Edit - I just read your question and it said beyond. Whoops. I had a mastadon account but I don’t like Twitter style social media so it was never used.
