Today Social Search is available to everyone in beta on google.com. But Google added social to Google Images, too. If you do a search on Images, you may start seeing pictures from people in your social circle. These are pictures that your friends and other contacts have published publicly to the web on photo-sharing sites like Picasa Web Albums and Flickr. Just like the other social results, social image results appear under a special heading called “Results from your social circle“. There are also two new links, “My social circle” and “My social content“. These links will take you to a new interface where you can see the connections and content behind your social results. Clicking on “My social circle” shows your extended network of online contacts and how you’re connected. Clicking on “My social content” lists your public pages that might appear in other people’s social results.
Google claims that social information can improve search so they will continue to improve this system. You can see in the video below how it works right now.
