One feature I wish Youtube had was a preview thumbnail that was made of 10 screen shots from key moments in the video, side by side. Would make it easy to filter out all the talking head. And right away see if its worth watching.

Does the video teach you something worth knowing? Feel like this could be answered by taking the captions and ranking the difficulty of the language used, or making a word map. Then have AI deciding is this about math, science, politics, and so on. Even simple as rating the words on a grade reading level would help to filter out useless videos.
