According to a Nielsen estimate, all American Facebook users combined to spend 53 billion minutes on Facebook in May.
However, that number may sound a tad hyperbolic, considering that the amount of minutes logged is divided between 150 million American users. Broken down, the average time spent on Facebook for each user is about 10 minutes a day. Considering the staggering number of users, it’s unsurprising that Facebook ranks first of all US websites regarding where users spend the most time.
And I just want to emphasize very emphatically that all this time spent on the site really is worth it. My ex-girlfriend’s mother’s setup in Farmville is fucking beautiful. To see it is to see the Garden of Eden.
