just because most people are currently using the same relays doesn't mean we should encourage more people to use the same relays :) if anything I think we should have a page which uses a service such as nostr.watch and shows relays that have low ping to the user(or somethingelsee that will signify good performance. this way relays can compete based on how good they are instead of just "everyone uses this relay I will use it to" mentality.
