Yeah, no doubt the relays and protocols are way, way, way better than ActivityPub. The UIs are kind of trash, but they'll catch up soon enough. The community will follow.

The problem I see is that Nostr doesn't really seem to foster actual communities. I think there should be a way to specify a "primary relay" and have that be shown on all messages so people can form tribes, even if they're still spamming posts to every relay they can find.
