the nostr relay model is a double-edged sword, especially if your client needs to aggregate data from a bunch of pubkeys: dump pipes makes writing and running relays a breeze but dumps all the complexity to clients. now you don't need a backend but you do have to implement caching, storage and indexing on the client side with subpar primitives (at least on the web) just to get a half decent UX. i'm convinced that clients centered around relays are the sanest way to build apps: @Jumble and @chachi embrace this idea.
