400 million people are now on Google+

Think no one is using Google+? Think again. It seems the social network is reporting record growth. Apparently 400-million people have signed up to Google’s social play. According to a post by Google’s senior vice president of engineering Vic Gundotra, 100-million people are now using Google+ each month counting its mobile apps.

“It was only a year ago that we opened public sign-up, and we couldn’t have imagined that so many people would join in just 12 months. While Google+ is all about creating a better experience across Google, it’s also a destination,” said Gundotra.

Following Gundotra’s post, users commented on the numbers released at Google’s I/O event stating that Google+ had 150-million users. Gundotra later commented saying that:

“The numbers at I/O were Google+ users all across Google. So Gmail users who used circles, or Android users who plus-one’d an app etc. were included. Today’s number of 100m is just on our plus.google.com destination site and the mobile app. Pretty amazing.”

Earlier this year Google’s CEO Larry Page said that the site had 90-million users at that time and that “+users are very engaged with our products — over 60% of them engage daily, and over 80% weekly.”

Google+’s biggest competitors Facebook announced that it had 955-million monthly active users in July. Though it all sounds like Facebook is winning the social race here, it’s important to note that it took the company a few years to reach 100-million active users, something that Google+ has achieved in one year.

Google+’s growth seems to be on a rocketing trajectory: back in June the social network announced it had 250 million total, this latest number suggests that the service is growing faster than ever.
