Google is always experimenting with new features aimed at improving the search experience. Take one for a spin and let us know what you think.

Join an experiment and you'll see that feature whenever you do a Google search. Note that you can only join ONE experiment at a time.
Google Social Search  
More easily find relevant blogs, reviews and other public content from your social circle.

Sign in to Google and do a search. If there's relevant web content written by people in your social circle, it will automatically show up at the bottom of your search results under a section called "Results from people in your social circle."

To see even more social content you can click the "Show options" link at the top of the results page and then click on the "Social" link.

What is your social circle? It's a combination of your Gmail chat buddies, your Gmail contacts friends, family and co-worker groups, and people you're publicly connected to on other social sites (such as Twitter and FriendFeed). Learn more about social search.
