I share your concern and it would be great to pick your brain on the issue, as we'll be facing it in absolutely every nostr niche. It's similar to the issue of Global, and the solution is probably similar - show apps recommended by people from one's contact list by default, or from some 'high-quality' list of people if user is guest.

And I'm not asking for any short-term commitment, just want to keep it as great-looking as it is now, and help it become scalable with nip-89.
