The Great Pyramid of Facebook

Facebook says that over 5 billion minutes are spent on Facebook each day (worldwide). Let's put this in perspective: each year humanity spends approximately 3.5 million person-years building Facebook. Mind you that this number does not include work hours of actual Facebook employees and independent Facebook application developers. For comparison, it took seven time less effort, "only" about 500 thousand slave-years, to build the whole Great Pyramid of Egypt, which served as a tomb for pharaoh Khufu (died in 2566 BC), the second pharaoh of the Fourth Dynasty.

Thanks to the advances in business methods, technology, and health care, we can now construct huge mausoleums in almost no time at all.
