John Dvorak is right about YouTube (damn, I never thought I’d be using the words “Dvorak” and “right” in the same sentence).
You wanna beat YouTube you gotta pass the BlinkTest. Next! Who wants to submit something for the BlinkTest?
One small issue - no matter how sticky the site is, what's the revenue model? They have astounding bandwidth and storage costs, and - so far as I can tell - no way to actually make money. YouTube may pass the "Blink Test", but I suspect that it fails the only business test that actually matters.
