Discovery is a broad term though. You mean getting noticed right?
Discussion
Getting noticed is only from the perspective of a new user, but even for older users, I had no clue nostr had so much content on such diverse topics until I worked on topics on pollerama.
On other platforms I check a few lists (i.e. circles or aspects) of people. Wouldn't mind having a few hashtags to swipe through (e.g. #artstr, #asknostr, #musicstr) as well.
Yes hashtags are hugely under-utilised discovery mechanisms
you can search 10015, so for one tag t you can find 100 tags and have notes from the tag
Is there a nip? Is it like related hashtags feature?
Basically you add interest to kind 1 feeds, the list is on nip-51 https://github.com/nostr-protocol/nips/blob/master/51.md
