It's sort of mutated into something else on nostr lol, but it is probably derived from the same place. It's no just 'no shitcoinery' it's also a bit like bitcointwitter culture is the gold standard or the only standard to emulate or something (I genuinely think some people don't know wider twitter exists outside of BT). I don't know lol.
It's got a bit better. Until there's a price move, and then it's unusable and indistinguishable from bitcointwitter.
It's been ok lately, Christmas has helped, no big price moves also helps.
