it would be good, if subs had a further category tree. maybe multiple even. for example a “Manchester United” sub should have sport>soccer. so people interested in that can subscribe to either sport or soccer to get posts from it, as well as from similar subs, instead of having to find and subscribe hundreds individually. on the other hand, sports haters could block/filter all sports, or just soccer, if they are fed up with it, instead of having to block them all individually. i’m sure that would enhance usability and wouldn’t interfere with how lemmy is used right now. it would just be some extra help.
