WSJ - Feb 28 - Google+ has become a robust competitor in the social networking space, with 90M users registering since its June launch. But those numbers mask what's really going on at Google+. It turns out Google+ is a virtual ghost town compared with Facebook. New data from comScore shows that Google+ users are signing up but then not doing much there. Visitors using personal computers spent an average of about three minutes a month on Google+ between last September and January, versus six to seven hours on Facebook each month over the same period, according to comScore.
