Nostr is flawed as a social network by design until they devise some way to create groups. Its the worst aspects of the Fediverse and the worst aspects of Twitter at the same time. Half your posts don't reach the recipient because they're not on your relay and you're just an individual floating in a sea of other assholes. There is no structure to the whole thing, on the Fediverse people that share interest go to specific instances, on Nostr you're just shouting into the Global timeline with the vague hope someone finds your shit interesting.
