Twitter To Surpass 500 Million Registered Users On Wednesday

Facebook might’ve hit the 1 billion user mark this summer, but Twitter is doing all it can to catch up: the network is poised to reach 500 million registered users as early as Wednesday.

In mid-January, we took a look at numbers from Twopcharts which suggested Twitter would reach 500 million users by February 26th. That date has now been moved up to the 22nd, as users are accelerating the pace at which they’re signing up for the microblogging service.
