The document introduces Open Stack, which allows for streamlined user sign-up and social integration across websites using open standards like OpenID, OAuth and OpenSocial. It describes how these standards give users more control over their data and social experience while allowing developers to write applications that can reach users across different social and publishing platforms. In the end, the document argues that while this new model empowers users and has promise for developers, the developer promises of the open stack still need to be fully delivered.
