IMO the coolest game changing technical detail about #nostr, is the fact that an account is JUST a public/private key pair. Its so simple its brilliant. One key, one identity, no matter which relays you talk to.
I feel like other protocols might scale better, though. ActivityPub, for example, is much more bandwidth efficient, which becomes critical as a network reaches the masses. I wonder if there is a future where Nostr takes on some of the properties of ActivityPub to help it scale to the masses, while not tying users down to any single server.
The future is bright. What a great time to be alive and online.
