Sometimes I feel like it knows which videos I'll like and don't like and it will purposefully show me 10 videos that are "meh" that I skip through quickly and then 1 or 2 videos that are spot-on (funny, intellectual, etc.) which makes it feel a LOT like a Skinner Box. Keep pulling the lever until you get something good, and all the bad stuff in between makes the good stuff seem that much better.
