“So if you take Wikipedia as a kind of unit, all of Wikipedia, the whole project--every page, every edit, every talk page, every line of code, in every language that Wikipedia exists in--that represents something like the cumulation of 100 million hours of human thought. … And television watching? Two hundred billion hours, in the U.S. alone, every year. Put another way, now that we have a unit, that's 2,000 Wikipedia projects a year spent watching television.” — Clay Shirky
