Silicon Valley's bubble in Facebook-apps startup has been our own local version of the crisis in toxic mortgage securities. With venture capitalists growing leary of the concept, developers have been eagerly awaiting the outcome of Facebook's FBFund, a grants program for applications startups. Results were promised on September 22, then again last Friday; Facebook still hasn't made a decision on the lucky winners. Why? Because Facebook's applications platform has become, like everything else in the company, a scene of rabidly intense politicking.Here's an update for anyone who didn't get the memo: Facebook's applications "platform," a set of software tools for embedding timewasting entertainments within the social network's pages, is not a level playing field. Some applications are more equal than others. That's only become clearer since Facebook foolishly put Facebook's platform in the hands of its top flack, Washington-trained bloviator Elliot Schrage. Facebook's Great Apps program, meant to designate higher-quality applications, has become a shameful excuse for nepotism . Awarding money on the merits is hard enough. When you mix in the need to help out your COO's brother-in-law's pet startup, or your ex-president's latest venture, it complicates matters. Is Facebook going to come out with a list of apps to fund that it's truly proud of? Or will this look more like an appropriations bill after it's made its way through Congress, larded with earmarks?
