Still searching for social salience
Now, links to posts from friends across the Web, including on Twitter, YouTube and Flickr, will be incorporated into search results, not hidden at the bottom of the page, with a note and a picture telling you the post is from your friend. So if you are thinking about traveling to a beach in Mexico that a friend has visited, a link to her blog could be a top result.
Finally, Google users will be able to privately link their social networking accounts to their Google profiles. Before, those connections were made public, which might have discouraged some users. People will see social results only if they are logged in to their Google accounts and have connected their social networking accounts.
