Blast you, Farmville. The most addictive of Facebook games is hardly even a game — it's more a series of mindless chores on a digital farm, requiring the endless clicking of a mouse to plant and harvest crops. And yet Zynga, the evil genius behind this bizarre digital addiction, says more than 10% of Americans have logged in to create online homesteads. How many hours of lost productivity does that translate to? Tough to guess. But for me, personally, at least dozens. Sorry, TIME.
