Chad Hurley, Steve Chen and YouTubers party with Pussycat Dolls in VegasYouTube cofounders Chad Hurley and Steve Chen partied in Las Vegas over weekend, taking to the VIP sections at Caesar's Palace and the Luxor, a nerdspotter tells us. At Caesar's Hurley, Chen and a crew of about 25 YouTubers — early employees, we hear — lounged around Club Pure, taking in a Pussycat Dolls show (an example in the clip below). Our tipster tells us the group partied not like rock stars, but "cool nerds." Anyone have a visual explanation of what that looks like? Send in your cameraphone spy clips of Chen & Co., or better yet, post them to YouTube.
