From the numbers on the site, it works out to 90 seconds of Facebook per day.<p>No really. This is useless.<p>Even if you assumed that 20% of the population uses 80% of the Facebook time, amongst that 20% you're at ~6 minutes per person per day.<p>Still useless. I spend at least that amount of time sitting on the toilet. More than twice that time waiting for public transit. I 'waste' 20 minutes every night lying in bed waiting to fall asleep. It takes me 5 minutes to make 'instant ramen'.<p>Ok, finally. Facebook claims 800 million users. Let's assume half of them are fake. That gives an overall average of just over half an hour per person per day. If we apply the 20/80 rule, the top 20% spend an average of 105 minutes on Facebook a day.<p>I guess that's a bit better.<p>The world spending 90 seconds a day on one task is... not really that ridiculous. I mean, I bet the world spends 90 seconds a day praying towards Mecca. (By rough math, it would require each Muslism in the world to spend roughly 10 minutes a day praying...).
