End Hunger, Ten Grains of Rice at a Time?

"Free Rice / for each word you get right, we donate ten grains of rice to a hungry person through an international aid agency."

I can think of worse ways to spend your time.

(Free Rice says that it is a sister site of the world poverty site, Poverty.com., and distributes rice through the United Nations World Food Program (WFP). FreeRice.com is registered by an individual, John Breen, of Bloomington, Indiana. I suppose that charities with massive staffs and east coast addresses are more impressive: but I don't have a bias against individual initiative.)
