Nostr 2.0 has arrives with the announcement of "Ditto".  Arguably, is the first of the  generation of apps.  Alex has indeed solved a LOT of technical problems:  Scalability, extensibility, speed, privacy, payments, moderation, portability, realtime, verifiablity.  

Dont get me wrong, I LOVE the first gen clients, and they are not going anywhere.  But for nostr to level up, we need ditto, and more things like ditto.  

Try it, run it, build it, create new specs.
