FreeRice.com Taking Off

I found this one via Paradigm Shift, check it out: FreeRice. It’s a simple concept. For every question you answer right, they get a page view and you kind of give (via them) 20 grains of rice. They pay for that via advertising. I needed to dig a little deeper into their numbers:

1. One grain of rice weighs about 20–30mg.

2. 20 grains of rice weigh about 0.6g

3. you need over 1660 plays on the site to play 1kg of rice

4. if I have found it correctly, one tonne of rice costs roughly $340, so one kg about $0.34

5. they need a cpm of 20 cents to come out even if they can buy wholesale.

6. based on their stats they gave 8,294,816,130 grains of rice, so

7. 414,740,806 hits on the site or 20 grain portions, however you want to see it.

8. Based on the 1660 plays above for a kg of rice,

9. they gave away roughly 250 tons of rice already

Not bad for a site that is only for just a little time. Let’s hope they do what they do :)
