Google+ Now Second Largest Social Network after Facebook, Members Now Exceed Twitter
Of course, Google+ still hasn’t caught up to Facebook. GlobalWebIndex estimates that Facebook’s 1 billion user claims are likely pretty accurate, making it not just the biggest social network, but comfortably so. And Facebook appears to be growing faster than Google+, too (33% for active user growth last year, compared to 27% for Google+). Twitter is also growing steadily, with a 40% increase in active users last year, but its membership is only 288 million, putting it in the fourth slot, behind YouTube.
