Google has announced that the user base of Google Plus has crossed 400 million and the monthly 'active users' has crossed 100 million.
Vic Gundotra, Senior Vice-President, Google, in a post in Google Plus shared, "Over 400,000,000 people have upgraded to Google+. This week we also hit an important milestone-over 400,000,000 people have upgraded to Google+. 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. And here too, I’m happy to report that we have just crossed 100,000,000 monthly active users on Google+ (plus.google.com and mobile app)."
