Free Rice group

http://freerice.com/content-group/end-hunger-57

this is my freerice group, you answer questions to earn rice for starving people, all you have to do is create an account > join my group > click on subjects at the top > select a subject > answer questions to feed people.

...That's kinda weird. Why do they have to wait for people to answer their questions? Why don't they just every rice they have already?

Thats what I thought, then again the company has to make money from site visits and advertisements to buy the rice and donate it.
