Earlier quoted context omitted.
YouTube’s algorithm isn’t very good for users because it doesn’t really separate mildly interesting videos that you finish from awesome content you loved. YouTube of course doesn’t care because they don’t make more money when you see something awesome.
It works pretty well for me. Do you use the like and dislike buttons, subscribe to channels you like, etc?
That makes things worse IMO. My favorite videos tend to be one-offs not channels producing regular content. Unsubscribing from everything definitely improved my feed.
