I agree normies is not ideal or fair. Mainstream or volume users is less negative. I do think the idea of Nostr thematic communities will be a better way to grow and differentiate it from X et al.
One giant worldwide Nostr which is heavily weighted to all things BTC wont work very easily. But micro social networks organized by communities or topical areas would allow people to find their tribe. Posts that are thematic stay on in that micro community and general posts where the masses would or may care could be funneled to a general purpose community which could be the highlight reel from the micro communities.
