Joseph Smarr at GoogleIO, June 2008: OpenSocial, OpenID, and OAuth: Oh, My!

OpenID, OAuth, microformats, OpenSocial, the Social Graph API, friends-list portability, and more will be discussed, as well as a coherent vision for how the pieces fit together and how developers can start taking advantage of them now.
