I honestly wish that Nostr succeeded because despite it's reputation, it's a brilliant concept. I think the biggest problems with the Fediverse are the fediblock culture and instance fatigue. Having accounts that aren't bound to a single server forces everyone to judge people on an individual basis and doesn't force people to create a new account elsewhere if their instance shuts down.

But of course, everything nice has to be ruined by pedos and scammers.
