Competition and user generated content

I somehow missed that one, but last Friday, it was in the news that Yahoo would be acquiring Bix.com, a portal for competitions of all kind. It's a 16-person startup company that basically seems to work by rating other people's content. Seems to be linked to MySpace, as there's the possibility to add a media item to one's MySpace account. So, what's the real difference between YouTube and this one? Not much, I suppose (and YouTube indeed does have user ratings as well), so I think that it's more about running after Google in order not to lose touch to what's currently hip. But what will Yahoo really do with this? What will Google do with YouTube? These questions seem not to have been answered yet. At least not really.
