I think relays should scale horizontally, meaning relays should become topic-based, geography-based, etc. Also, I also don’t think relays are under the obligation to store notes forever. Part of scaling horizontally is hosting your own long term storage (or pay a provider to do that for you). If a relay needs to scale vertically, they could start charging for access or do data mining+ad injection, all kinds of stuff to monetize. One of the writers of the NIPs posted this earlier today: > Other relay ideas (not very good, just to sparkle your imagination): - a relay only for people with top-level domain names (no "@" at the NIP-05) - a relay that only stores the most recent post of people - a relay that only stores posts that have received at least 10 replies from other people (big threads) - a relay that only serves posts to people having $X tag on their profile metadata
