Honestly, this makes no sense. It doesn't matter how famous you are - if your product sucks, people won't use it. Look at Ashton Kutcher's Blah Girls. It's a miserable failure - even though he's much, much, much more famous than a mere Kevin Rose - because no one really needed to see cartoon girls do a weak TMZ imitation.

I think people like to chalk up Digg's success to Kevin's "celebrity", where in reality, he's a nobody and Digg actually is a really, really good product for the niche it's serving.
