Showed a friend of mine Nostr and the overall concept.

That really blew his mind was seeing the other apps and “taking your identity” across apps after showing him Damus, Primal, zap.stream, highlighter, and habla.

As we find more uses and apps using Nostr the identity portion will be a real selling point.

As other people have mentioned not everything has to have every component on Nostr but identity will probably be a big piece.
