I googled to find more about quadrillion comparisons (because that pennies to Saturn remark was cool) and this post is the 6th hit when googling "one quadrillion"!
Just for comparison, if Sillytech were the quadrillionth hit, assuming 10 hits per page, and a liberal 1 second per page load, it would take 3,170,979 YEARS to reach the page with that hit. That is approximately how long human beings have existed on Earth.
