Yeah, with a small amount of effort you can really make your YouTube feed work for you. I have a main account full of engineering, computers, and misc entertainment (sketch comedy channels + Atrioc) and a separate one for my work laptop that's just music. Both feeds are pretty fantastic but the recommendations on latter is especially good - I've found a ton of new artists including some with only a few hundred followers (shout out to folk singer Alexander Guy!)
It might take some time but if you don't want to start fresh with a new account, mark everything you don't want as Not Interested as they pop up until your feed is clean! It's worth the effort imo
Yeah I think I can, but I find that unfair to the content creator who may have otherwise created a good video. What I may end up doing is turning off video history, but sometimes it’s useful to easily pull up a video I’ve seen recently.
