Let me explain what I mean with an example.
You visit a new website, you can have 2 scenarios:
1) Register with email, password
2) Login in with Nostr
For a Nostr user, do you think they have the same appeal? The 2 has less friction, so higher conversion.
For a non Nostr user, see the same logo in several contexts reinforce the idea that this "thing" is sometime valuable, so push to try/learn more about it.
