Agreed - but very different audiences / population sizes though.
Atproto has 38m+ people; it will have more diverse content probabilistically
Nostr is much more niche and more people are here from an ideological perspective, so the content converges towards the ideology
Hopefully we reach a point where apps are built on these protocols without people knowing/caring; they're just apps that work in the way they want them to and diversity takes care of itself
But yes, I'd love to find more "normal" people on Nostr who enjoy topics outside of btc
