That buzz you hear is the result of Google's unveiling of Google +, its newest foray into the social arena and, hopefully for Google, its answer to Facebook. The product was rolled out to a limited number of users on Tuesday.
The main difference between Google + and Facebook? Google's use of "Circles", where members of Google + can literally drag and drop their contacts into different social circles. Google touts Cirlces as the "easiest way to share some things with college buddies, others with your parents, and almost nothing with your boss."
Needless to say, there are already hundreds of articles on the newest challenger to Facebook's social media throne. One of the best can be read here.
Is this too little, too late for Google in attempting to grab some of the audience (and massive advertising revenue) away from Facebook? What do you think?
