Social networking sites and blogging sites are a big part of U.S. culture and even social culture around the world. Now, Google has a searching mechanism called ‘Social Search’ which allows you to search for results the relate to your specific circle of friends.
This circle of friends is generated from:
your gmail contact list (so you must be signed in to see the effects of this feature)
social networking sites linked to your google account
