Googlified

Google released a new API called Social Graph API today, allowing users of the API to find out the “public connections (friends, coworkers, etc.)” of a URL (of a blog, social networking profile, sgnodemapper, etc.), email address. The information are determined by the “XFN, FOAF markup and other publicly declared connections” on the web page. You can specify the API to return either URLs that are linking to your input URL or URLs that you (your input URL) are linking to.

Here are some example applications Google created and this is a sample data of other sites linking to some of my social networking site profiles and my personal website (shameless linking!).

I am going to spend a few hours to play with it, see what cool things I can come up with. :)
