This site donates 10 grains of rice for every question you answer
(www.freerice.com)
A serving of rice is at least 5000 grains.
The site is a good thought, but there are much more effective ways to spend your time if you want to make the world a better place.
They unnecessarily serve huge image files. Wasted bandwidth.
we used to use this website in elementary school to practice for math n such. great for kids!
A place for your preferably unique useful or fun sites and kind of a bookmark manager for me :p
