I watch stuff on YouTube all the time--but things I'm looking for--a specific music video, or a clip from a movie.
I've never even heard of this.
I guess I'm just too old.
I usually don't watch these specific set of videos, but they are always on the top rated or most viewed. So I guess if you don't go to that part you wouldn't see it. I tin to randomly play videos that I find on the lefthand side column of the video I just watched.
