Hm, that makes sense, nevermind then.
It doesn't actually make that much sense. I seriously doubt that they are only making 3.3 cents for each adview from the companies they have sponsoring them (which are all huge names), so even IF (they don't, but IF!) the grains of rice cost a penny each then there is a lot of money that is going into the webmaster's pocket.
I brought this up before because I think it is pretty important. The companies are probably sponsoring the site to seem charitable, but there is probably a huge amount of graft. I like the idea of things being given to poor people, but I don't like that there is a very good chance that some fatcat is probably laughing all the way to the eBank. Seriously, did anyone read their FAQ? It's so full of guilt trips and shit "It's FREE RICE you want to give FREE RICE to STARVING kids in a THIRD WORLD to save their LIVES RIGHT?! You're not some RICH GUY who doesn't want to HELP STARVING KIDS?" that there just has to be more than meets the eye here. I mean, those ads to sponsor children in 3rd world countries are full of guilt trips and stuff, so you might expect it; but this site isn't trying to get our money or anything so I would expect them to be a bit more subtle in their explanation of the site's goals.
I don't know, it's fun and it probably does help, but I still can't see how there isn't 100x as much food being generated by the huge number of pageviews they must get.
