Welcome to the Social Graph Resource Center. The social graph is a phenomenon of nature, the mapping of connections and relationships among people worldwide. This Resource Center focuses on the social graph and its relationship to social networks, such as Facebook, MySpace and others. Mark Zuckerberg, CEO of Facebook, defines the social graph as a network of connections through which people communicate and share information. Facebook's April 2007 announcement of the Facebook Developer Platform brought the social graph and building social applications to the forefront of web development. In October 2007, Google responded to Facebook's initiative with its announcement of OpenSocial, a common set of APIs for social networking applications, which are portable on any social network that is a partner of OpenSocial. This may lead to an open social graph on the web, which would create exciting possibilities for application developers and probably some controversy, especially regarding privacy issues.
