After glancing through the top few, I quickly went for the search box. To their credit, once I do a few searches, the recommendations drastically improved when visiting next time.
A side effect of this, of course, is that you can study all kinds of stereotyping and biases by repeating my experiment in various regions I suppose.
Yes, I watched a bunch of Dota replays during a recent tournament. No, I don't normally go on youtube. So I watched a daily show video clip that was linked. All my "watch next" and "recommended" are Dota. That's not smart, that's aggravating. I would have been ok watching a couple more ds clips, but instead exclusively bad recommendations were made based on poor data.
I dislike the idea that my world gets filtered by algorithms, but I really hate when they're obviously bad at it. Although I suppose I should be grateful that it's easily spotted when it's bad?
