Nostr brings that caos back to some degree, due to its public private key nature. People may lose/ spin up new identities at will. Different servers which may or may not have certain events.

Indexing/ search basically does not exist to my knowledge.

Havent tried but try finding a certain discussion on nostrs early days about a nip design would be difficult. No wonder that's why people still use centralized services such as github and telegram plus more for planing and "higher level design" than nostr at the moment
