Online video Web sites are popping up everywhere. So why not add one more to the mix? Arik Czerniak, CEO of Metacafe .com, says the site is the "Prada of online video," because you'll see only the "best" videos on the site.

Metacafe users review, filter, and rate thousands of new videos each day and the top videos are quickly distributed to viewers.

I watched some of the videos on Metacafe.com (for testing purposes, naturally), and can confidently report that it is an effective way to waste time.
