Going through an old list of ideas for nostr, and almost all of them have been done since then. Fantastic to see people thinking along the same lines I am, disappointing that I didn't get to do any of them 😅 - [ ] Second-layer relays that aggregate posts from particular groups/users - [ ] Relay as a service - [ ] App for migrating between relays - [ ] Mirroring services that crawl popular relays and check for the integrity of your historical notes, then reposting notes to new relays if there aren't many copies left in existence. - [ ] Calendar events on nostr
