Last year, Google unveiled its Social Search and launched into Labs. The idea is that you would see blog posts and other content from your social network in your search results.
Now, the feature is being rolled out to everyone as a new beta feature of Google.com. As part of the release, Google has also integrated social search into their Image search. You'll see pictures from photo sharing sites such as Flickr and Picasa.
The images will appear under their own special heading. You'll also notice links to "My social circle" and "My social content." Click on either of these links to discover your social network as Google defines it.
To truly experience social search, you'll want to create a Google profile, where you can list your various social networks. This helps Google find your network and connect them to you in their new social efforts.
