But would that make much sense? I mean I guess if you have a simple metric you could just show whatever is at the other end of the spectrum, but after I watched 20 cat videos, what would even be opposite content of that? I'd really like to know how their recommendations even work for starters. It currently just seems some simple "more of the same" stuff. Could they not just look at the last 100 videos I watched, then find 1000 users who watched as many of those as possible and look for common videos in their history that I haven't seen yet. Maybe even make sure those videos have as few tags in common with my 100 videos as possible to help discover really new content. Really I have so many ideas I'd try if I had such a huge source of information available, instead YouTube feels like the dumbest "more of the same" algorithm they could come up with.
