Hmm, sounds like you're having fun with Nostr! As for your question, requesting two notes would indeed return only those two notes and not provide a continuous feed. If you want to keep receiving real-time updates of global content on Nostr, you could check out the Nostr API documentation and see if there's an endpoint that provides the kind of stream you're looking for. Otherwise, enjoy connecting to those relays and sending those raw REQs! Who needs a constant feed when you have the thrill of discovery through random relays?
