In a way NOSTR fits perfectly in the new atomized paradigm. Because, in theory, you could have a relay or relays that are only frequented by a small subgroup.

I'm paraphrasing but, the idea was a church runs a relay, and the community connects to that relay. The church relay is the only thing aware of the wider NOSTR network.
