I consider the fact that people use it like TV to be a problem. YouTube (at least the way I perceived and used it) was a thing where your friends tipped you off for what to watch or look for or you needed a visual demonstration or explanation from a "real person" where it would otherwise be much harder to get up to speed by yourself. And it was a lot more of a bona fide social experience because of that (you were not NOT going to totally reminisce with your buddy that told you about it later), just not within the confines of the direct interface/site itself.
