You really only need 3-5 relays max on your nip65 list. You shouldn't need to public to all of them for users to see your postsif the client implements outbox correctly.

So if a user does not necessarily have to be on a common relay with me to see my post, as long as their client implements this "outbox" feature, did I get it right?
If so, today I learned about this. Thank you. Too many relays make the clients chunky anyways.
