I don't know where to talk about this, but I have to get it out there. I have a great finding to share. It is absolutely ridiculous to rate according to how many thumbs up there are, because videos always have 90%+ of thumbs up, and it doesn't show the actual quality of the video.
My system is to look at the proportion (thumbs up)/(thumbs down). On an average video, you'll notice that ratio is 20. Very commonly. But for exceptionally good videos, it'll have 30, sometimes 40 ratio. We can better see if a video is merely good, or exceptional.
Everytime I watch a new video, I do the calculation in my head, and it's annoying that it isn't the default rating system. It should be the default, because it is just more efficient, and it's not complex.
I wish people could upvote this and that it'd be seen by Youtube people. Thank you
