I’m really interested in what other applications nostr can have outside the obvious flavors of traditional social media.

Some ideas:
- workout client (posting your run/climbing session/weights/whatever to share as a part of a community)
- review/recommendations client (I’ve got TV shows/films/books/podcasts all in different places and it sucks)
- locally (governmentally?) run read-only relays for public announcements (weather warnings/traffic announcements/bus gps/amber alerts)
- IRL loyalty programs
