nandemoari writes "It seems the world's most popular social networking site was just moments away from acquiring another — and few of us ever knew about it. A Facebook executive has revealed that a planned takeover of Twitter only fell apart because of a disagreement over stock valuations. Despite the rather miserable economy, Facebook is still looking to buy out other firms and says it could make a billion dollars a year from advertising. Peter Thiel, a venture capitalist who put up some of the money behind Facebook, discussed the deal in a Business Week interview. Thiel says the two sides agreed a $500 million purchase price and that Twitter would receive the payment in Facebook stock rather than cash — which is a common solution in large takeovers where there simply isn't the money available for a buyout."
