Google+ Has 100M Active Monthly Users
 

Google's Vic Gundotra says that Google+ now has more than 100M active monthly users. I have no idea where all those people are but I'll take his word for it. 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).
