Why does it need to be specific relays? A better solution would be for NOSTR to introduce a NIP where users can specify their country, state, city, etc., and this info gets propagated across all relays. That way, we wouldn’t rely on just one relay; every relay would have the same data. If one relay goes down, the info is still available on others. This eliminates the need for country-specific relays entirely.
Relays are just a place to store our notes and data, relays are not going to become a community
