Hmmm yes. I like the idea of adding additional (poster defined) feeds. Then users can just enable or disable various feeds when viewing a profile’s content. #[7] unit default feed on profile would include all notes but you could define various sub feeds that you can add *or remove* posts from. Idk if this can fall under a currently existing nip/kind. You can, while drafting a post or afterwards, add a note to one of your custom feeds. And later remove or recategorize (update the sub feed list of note IDs?).
Discussion
Users could subscribe to your default feed or modify what they see it to exclude certain of your sub feeds
I was always under the impression that eventually there’d content specific relays that do some filtering for you, and I imagined a way to choose which relays to post content specific notes to, and which to read from (which Damus already allows in global).
