Trivia and Free Rice

i just found this site, and i'm totally addicted. it's called "free rice." all you do is play the trivia game and for every right answer, they donate 10 grains of rice to the UN world food program. i'm such a trivia junkie, and this keeps me sharp and teaches me new words, etc. i'm so addicted, i can't stop. which i guess is good, because it creates more ad revenues for the site, and therefore donates more rice. it's a win-win situation. huzzah for marketing and capitalism!
