Nosta now has a dedicated relay at wss://profiles.nosta.me (running strfry, check on nostr.watch). It only accepts certain kinds:

0 - basic profile info
3 - follows
30315 - user status
30078 - application specific data
10002 - relay list

Goal is that this relay can be a reliable source for the most basic profile info. That way the client doesn't have to so work so hard to figure out which of the thousand relays a profile might be on. To keep this efficient, it rejects all other kinds.

Ideally, this relay automatically fills its database with non-spam profiles it finds on other relays, so it can be as complete of a set as possible. Someone would have to write that functionality thought, I can't do that.

The first step for Nosta is now to always connect to this relay and use it for lookup of certain kinds, and also publish those kinds (like during profile creation).
