Ciantic, 
Good Jack Dorsey interview: https://www.piratewires.com/p/interview-with-jack-dorsey-mike-solana - he just fails to see that Nostr or any other protocol won't survive without a hit application.
Bluesky's Paul Frazee's answer is a good take on it: https://bsky.app/profile/pfrazee.com/post/3ks3iv5iwqs22 - Bluesky wouldn't even exist if they were doing just protocol.
