Google Social Search is now updated and integrated well into web search. Google Social Search helps you discover relevant content from your social connections.
Google social search results is now mixed throughout the regular search results based on the relevance of the item. Social Search is now comprehensive with notes for links people have shared on Twitter and other sites.
For example, if you are looking for a video of U.S. President Obama on “The Daily Show” and your friend tweeted the video, that result might show up higher in your results and you will see a note with a picture of your friend.
