I understand. I was sorting of thinking tied in with a way for clients to show new people something beyond bitcoin. I think that is a lot of people's impression of Nostr (perhaps not all that inaccurate, it is predominantly this maybe). Personal discovery will always be there imo cos algos won't pick up on everything. (Hashtags and topic-focused clients help somewhat too for discovery.) 

 What I would really like are clients with an "advanced search" feature. It could make the scouting of the Nostr universe more efficient and effective. E.g. search profile description only, search post with videos, ... 

 Yes, that would be very useful. I think eg searching for people with a substack as their website link could bring up interesting people, potentially at least. But yeah, there are many possibilities this could be useful for
