Through programs like Google's AdSense, OpenSocial and their increasing pool of so-called "web gadgets", "social gadgets" and other Google-hosted services many web sites on the Internet are effectively feeding user information about sites visited by the users, and now also their social connections, to Google.
Through OWF, Google and Facebook now have an appropriate venue where they can resolve their differences between Facebook Connect and OpenSocial platforms, as well as work on a standard way to have their users interact with each other.
