Twitter killer isn't Nostr, or any of its many great clients. fElon Musk is.

Nostr is the protocol which's giving us the opportunities to take control of our identities online, for social networks but not only... there's plenty to come... but don't just wait for it, jump into it!

Nostr did not go live on the app store, but Damus, a nostr client. 😌😅
