Youtube as we know it won't last very long because of of the copyright issue. Google want it to remove all the copyrighted content, like South Park, music videos, and even silly people doing crappy karaoke in their living-room.
It kinda sucks. I know the company who produce such shows want to make more money, and that's basically what it comes down to. But it wil probably mean that, in time, Youtube will be the new Napster. I.e., crap.
And that, in all likelihood, you'll have to pay to access most of the decent videos on Youtube.
Selling out sucks.
