When we look at individuals spending a few minutes or even an hour a day on facebook, it doesnt seem like its such a big deal, but when you figure out the math like I did, you release how much human productivity is completely wasted on it. Here is the math. 900 million users and lets say they spend 5 minutes average per day on it. (yes, some spend hours, but some also dont log on for days, so lets just say 5 minutes for this example) Thats 4.5 billion minutes wasted on facebook. How much is 4.5 billion minutes? It's 75 million man-hours. Or It's 3,125,000 days Or It's 8,555 years. 8,555 man-years of productivity wasted every single day on facebook. Over the next month, over 256,000 years will be wasted on facebook. What could the people of the world accomplish with an extra 256,000 years of time?
