CONFONZ — Would you believe that M.C. Hammer is still alive? When not dancing his heart out at his Oakland church, Hammer spends his days using a Mac and jumping out of airplanes with nothing but his famous pants to save him. Further more, the man now has a startup. It's called DanceJam , and you're not cool enough to see it yet. Rumors on the IntarWeb state that the site will be a YouTube clone focused on videos of people dancing. But wait! There's a value add! If you upload your dance video, Hammer will watch it and rate your moves. Look for this site to be a goldmine for embarrassing blackmail footage when it launches later this year.
