Define a word, save a life...

Today we were forwarded one of the coolest sites we've come across yet. It's simple, fun and effective, not to mention thoroughly addictive.

FreeRice.com, a sister site to Poverty.com, combines global altruism with a voc to help save the world, one wordabulary test at a time. The premise is simple as can be: Choose the correct definition out of four choices and 20 grains of rice are purchased to support the United Nations World Food Program. So who pays for the rice?

The rice is paid for by whose names are at the bottom of the vocabulary screen. Each time you define a word correctly a new banner appears. So the advertisers are paying for each click on their ad page, which is going directly to the WFP. And you're getting progressively smarter to boot. Could there be a more ingenious site? We don't think so.
