Yup 🎯 Apps reading from a set of relays defined by the Communities (or the App's goal). Solves the global state problem too, at the local community level.

We have community relays (theforest and thecitadel) and I integrate the person's local relays, and we have a set of non-spammy relays like aggr.nostr.land and nostr.wine, that I use to include npubs that aren't on our relays, but are on someone's lists (I just include all lists, including follow lists, and there's a filter where they can select which ones to include.)

The novelty is that I let you post notes as zaps, on a relay you normally can't write to. TheForest is closed to any npub who isn't whitelisted, but you can zap your way into the feed. It's also interesting because people can like, comment on, repost, highlight, or zap your zap. Or report it. 😅 It just looks like a reply. I've also thought about using zaps to upvote replies, into the zaps list, at the top. Like, cumulate the zaps. Then people could vote for the replies they like best, with money. I'm experimenting with making zaps more functional, basically.
