In a press release today, Yahoo! Inc. announced they have agreed with MySpace, and Google to form the OpenSocial Foundation "to ensure the neutrality and longevity of OpenSocial as an open, community-governed specification for building social applications across the web." "Yahoo! believes in supporting community-driven industry specifications and expects that OpenSocial will fuel innovation and make the web more relevant and more enjoyable to millions of users," said Wade Chambers, Vice President - Platforms, Yahoo!. The move is a bit surprising since the OpenSocial initiative was a Google brainchild, and the two are arch rivals. The press release quotes both MySpace and Google representatives but the real question is what does Microsoft think?
