As you know, I've been on the fediverse since the kiwifarms.cc (rest in piss) days, with my last account being on Gleasonator (the .com version, not the .dev one); I left it fully for Nostr because Nostr does what the fediverse does better, and once Gleason created the Mostr bridge I didn't have the void made from not having the fedi folk I liked interacting with present anymore.

Not to say that Nostr is perfect (it's not), but it's a hell of a lot better than the fediverse is presently from a federation and interoperability standpoint.
