I agree but I like the domain instead of user at domain. But we render it shit work _@nos.social or _@rabble.nos.social vs nos.social / @nos.social & rabble.nos.social / @rabble.nos.social 

The username@nip05.server looks like an email. If we did username.nip05.server it could both be a web view profile and a nostr name. 

Anyway I think nostr names / addresses is way better than npub / nprofile sharing.
