Ok, you have to be signed into Google.com to get the social circle or social media results but get ready for Google Social Results. On January, 29 2010. Social search is now LIVE via Google. Still in BETA Google search now accesses your social media circle in an attempt to display realtime content for improved relevancy. Notice that Facebook was left out. This is due mostly to that most of the content on Facebook is private, which is good for user privacy – but maybe not so great for businesses trying to be found on search engines. Interesting that the search would not at least access “public” pages of Facebook. Fun stuff. Social media – old term but still showing value as integration ramps up.
Great article on the details here. http://econsultancy.com/blog/5332-google-social-search-goes-live-without-facebook-results
