After Facebook garnered more than 1 trillion pageviews per month, now it’s Google+ to mark 50 million users in 88 days – Google+ record fastest growing social media network ever. On September 20th, company announced its first API and made it openly available for all internet users to sign-up.

In a new Google+ post from Paul Allen, who has been tracking the user growth rate of the service with his own mathematical formula, he claims that Google+ likely broke the 50 million user mark on Sunday. He states, " ... since being opened to the general public (over age 18) last week, Google+ has been growing by at least 4 (percent) per day, meaning that around 2 million new users have been signing up each day."

I really love Gplus. The only reason I don't spend too much time on it is because most of my friends are still on Facebook.
