@MrsPramm - I don't know about that. Some of the viral videos I've seen have been interesting only because of the culture and memes that have built around them, rather than because they are that interesting themselves.
The Star Wars Kid for example, is kind of a mean spirited thing to post and not something I'd want to watch on its own. I don't know how it got popular, except that some people are jerks. But some of the remakes have been really cool, because they aren't just based around making fun of someone.
