My lifetime friend Charley directed me to this site, probably because he thinks my vocabulary needs some work. It's very simple, very well designed, and a win-win situation. So what is it?
It's a simple English vocabulary quiz where, for each question you answer correctly, the website donates 10 grains of rice to help world hunger. That's all there is to it. The design is such that it's a very addictive "game". They show you each grain of rice that you've won and the questions never stop, so it's hard to quit. Not to mention the guilt you feel when you get one wrong.
The only downside I see is that they've stolen the domain name I wanted for the site I was planning called "Freer Ice" about reducing the consumer cost of solid water.
I'm really impressed when people find even a tiny solution to first world apathy/ignorance about the hunger crisis. Send the link to your friends, especially the wons dat ain't talk real good.
