What do you think about an event kind for "read" that could be sent automatically whenever a user reads something? Probably not worth doing for notes, but for stuff like videos, podcast episodes, songs, articles, recipes etc that could be powerful material if a user wants some algorithm to detect what they see more and use that information to craft custom feeds on their behalf. nostr:npub1utx00neqgqln72j22kej3ux7803c2k986henvvha4thuwfkper4s7r50e8

I personally don't want that for myself, but of course it would be optional and clients and users could decide to not emit these things.

Or maybe there is some cryptographic magic that allows something like this to be achieved in some shape or form without revealing too much about ourselves? nostr:npub1vadcfln4ugt2h9ruwsuwu5vu5am4xaka7pw6m7axy79aqyhp6u5q9knuu7
