"Evolution of Dance"

I'm always curious about the nature of a hit. Some of them seem bound to happen, others I really couldn't predict. The "Evolution of Dance" video for instance. Sure it's big fun, but I'd really not have imagined it as a number one hit video on the Web.

I was led to this from an article about how YouTube has decided to share revenue with its video creators. I am surprised by this. Sure, the big hit videos has the potential for big income by ads or other things, but it is only a potential. And I thought that YouTube was still a big money drain, due to the huge site-running and bandwidth costs such a site has. I dunno, I suppose if they decide to share the money, they must have some.
