I have similar thoughts but I ultimately think it’s a bad idea; one of the powers of nostr is the portability of the social graph and starting from scratch on each use case breaks a lot of what’s cool about it.

That said, being able to fork your follow list, or have some slight modification to your kind:3 could be very cool and depends a lot on the use case.

FWIW, I don’t think it’s a per-kind follow list, but more a per-use case list, like I might be interested in someone’s thinking and want to follow them and also follow their highlights, long forms and podcasts but their music taste sucks and I want to not have them in my music follow list.

Agreed on paragraph #2. I changed my opinion recently about this and I think it solves some problems.
