It's basically what Nostr could be if they started over from scratch. Nostr is busted. It started out simple and now it's a mess of laggy and incompatible NIPs, relays, and clients. The only usable app on Nostr is Primal, IMO (nice work!) Pubky learned from Nostr's flaws and built a decentralized system architecture that addresses these critical issues. Also, it has really cool and innovative features and a great UI/UX. They just released a stable and decentralizable stack - that's why I'm shilling it so hard now (and I'm fed up with the bots here). There's lots a great people and projects on Nostr, but it's become obvious that it's a dead end (and kind of a cult). The smart, open minded builders are gonna start building their new apps with the Pubky SDK (which is already better than Nostr's and will significantly improve in Q1/Q2)
