Really? I bet they are way, way off. "To arrive at the estimated $360 million bandwidth tab for YouTube, the analysts assumed the site will receive 375 million unique visitors in 2009 and that a maximum of 20% of those users are on the site at any given time." There's no way 20% of visitors are streaming video simultaneously. I doubt it's even 1%. Kongregate maxes out at about 0.5% of its monthly uniques connected to chat at once.
