FreeRice.com - Word Games and World Hunger

FreeRice.com, sister site to Poverty.com, has a novel way to fund work in donating food. People play a vocabulary game, matching an increasingly difficult set of words to their meanings. Every time you get a right answer, the organization donates 10 grains of rice. It's driven by advertising, so the more words you get, the more ads come up, and the more money they get to turn into the grains of rice. Started on October 7, its use has been growing exponentially. So, go do some good and run into some pretty interesting words.
