Click to viewCameron and Tyler Winklevoss, the twin cofounders of a college social network which is not Facebook, finished second in today's Olympic rowing semifinals, just behind the Aussies, and will compete in the finals on Saturday. It was quite the upset. Previewing today's race, Row2k.com wrote that "the Aussie pair is a lock," that "Serbia, Germany, Italy are the like contenders for the final two qualifying spots," and that the ConnectU cofounders "have their work cut out for them if they want to win a spot in the A final." While they were winning in Beijing, they lost a battle in court.The pair alleged that Harvard classmate Mark Zuckerberg stole their idea in creating Facebook, ended up settling, and then appealed over the terms of the settlement; a judge denied their request. But if their long-fought legal battle with Facebook proved anything, it's that the JFK Jr.-lite Winklevoss brothers never quit, even when everyone — including judges — thinks they should. Take that, Serbia! (Photo by Getty Images)
