Marissa Mayer, VP Search Products & User Experience at Google, announced a few weeks ago a Google Social Search will be introduced; this new project launched will be a Google Labs experiment. With Social Search is information created by your contacts integrated into the Google search engine. An example was given with a search for “United States”. It then delivers regular search results with content of friends between them as one Gmail message that refers to a FriendFeed update of another friend.
Before Social Search can be used you would need to have a Google user account and a Google profile (available, as it must be public) people are available in Google Contacts.
While the complete details of the search are still hidden, here is what we currently know (and we’re still updating, so bookmark and come back for more information):
– The bottom of search results will soon have social networking information from your friends, like their Flickr photos or their status updates. It’s blended search integration, similar to seeing news or image results.
– These are pulled from social networks connected to your Google Profile. The more that are connected, the more social information that will appear in search results.
– They have also improved searching for images using social networks. Images become more relevant using social networking data.
– It will be initially launch in Google Labs in the next few weeks.
UPDATE:
On Flickr there is a screenshot posted of Google Social Search. The picture shows that between the results, displaying results from your “social circle”. Two results are being shown, both of FriendFeed.

While half of the announcement was made by Marissa Mayer, Yesterday was the message that Microsoft has signed an agreement with Twitter. Following them now Google has an agreement signed with the micro-blogging service.
This means that as this is the case for any Bing tweets available to Google and diving so soon the messages in the search results. This way you can quickly search for current information.
For example: If you want to know how the weather in a given place you get to see tweets from people who are there at that time.
