Popular videos I don't bother with, but sometimes I see a girl with like 400 views who put out some really good content and some douche is telling her to get the fuck off the internet because she's not attractive, or can't talk about geek culture or analyse anything because her tits will get in the road, and I kind of A) want to verbally abuse the shit out of that pile of human dross, and B) give some encouragement and let the user know that their content isn't completely taken for granted.
I don't mind youtube, I just wish they'd fix some of the problems with it.
