This is what we need. 
Personal relays: It only stores my posts, but everyone can see my posts by joining the relay.
Household/town relays; if I know you in person, we have our private relay
Community relays; if we like the same thing, we share a relay, maybe we even pay for it. 
Public relays; Gossipstations

Freedom ain't free. If you want to keep the comms up you have to host it and pay for it. Free gets you noticed, but the people who pay are here to stay.

Is there a way to teach nostr clients to prioritize loading specific relays? And then yeah, it'd be nice to see what relays people are on publicly so you can get max connectivity.
