You're doing a lot and the integration into browsers is very helpful 🤙
I'm thinking new users and going outside of their default browser might be too much. It's the same in my case. I seldom go directly to nostr.band even though that's the way.
How I do it? Just by browsing the feed and discovering new people by their notes and interactions. Nostr is getting so big so finding the right type of people is more thematic like in the traditional media (Twitter etc.) .
The issue may not be even the discovery but that the current nostr populace is too homogeneous.
Here's a capture from Primal just now:
