Google Social Search left the “beta” label and it’s live and ready for you to use now, and you can check out your social circle and find out who in your network is sharing public stuff, I found this information on Google official blog and though to share it with you. You can check out your social circle directly by visiting this link and see what’s going on there, maybe it will take some time for the connection and content to update.
I am sure that most of you have an account on Google, so If you want to get the most out of Social Search right away, get started by creating a Google profile, where you can add links to your other public online social services.
