Google+ turns one year old tomorrow, and to celebrate, Google has announced that there are now 250 million Google+ users worldwide. 150 million of these users sign on once or more per month, and of those users 50% (75 million) sign in daily. Each user spends more than 60 minutes per day on Google products, and it ends up that most people who visit Google+ are doing so from mobile devices. People on average spend about 12 minutes using Google+. To respond to the mobile demand, Google today announced Google+ for tablets. "We think it's the best version of Google+ we're ever designed," Google Vice President Vic Gundotra said.
