The google social graph can be found at http://socialgraph-resources.googlecode.com/svn/trunk/samples/findyours.html. It can be used to see how web sites are connected to your profile, web page, or email address. One way to increase this connectivity is Google Profiles. For example, if I input my blog, it spits out my youtube and picasa accounts.
