The law firm Morrison and Foerster’s Socially Aware Blog have managed to gather the relevant data on how much time one spends on Facebook, Twitter, Google+ and other social networking websites.
Google+ gets about 100 million active users per month, while Facebook comes in at an impression 1 billion. This data has been translated into how many hours these networks are used.
It seems that the average user on a monthly basis spends close to 7 hours on Facebook, and a rather meager 3 minutes on Google+. Interestingly though it seems that their data has revealed that on average users spend only 21 minutes a month on Twitter.
