Running relays does not cost much compared to client development costs or relay development costs. But yes there should be an economy starting for things to be sustainable in the long run.

Right now a dozen (for the sake of decentralization) 20$ / month machines can carry nostr. Maybe add couple 30$ "historical" relays to keep the old notes and that's it. There are not many notes.

"Zap sharing" was done by snort and I got some zaps from there. Cool feature.

I think relays should adopt freemium/premium model. What do you think?
