The algorithm mostly suggests stuff I enjoy watching. I suspect the key is to avoid like the plague to click on anything that's clearly "engagement bait", and to subscribe to stuff I enjoy.

The suggestions I get look good too but I'm rarely just looking for anything interesting to watch, I want to watch something specific.
