Unfortunately, everyone browses YouTube. And there's a lot more not-smart people than smart people. (And teenagers have a lot more time on their hands than adults.) I'd argue the root problem of YouTube comments is that they're not associated with any real community at all, in most cases. There's almost no benefit to posting a good comment, and no penalty to posting a stupid one. Imagine how stupid the comments would be if everyone watching a TV show with you could post to the same wall.
