Who wouldn't want to make money for their great games? Online "casual" web-based games have been extremely hard to monetize, historically. The standard route has been to monetize with a preloader advertisement. Unfortunately, these advertisements have extremely low click-through, and ultimately, do not generate much revenue unless multiple millions of people are playing your game everyday.

We think game developers should make money based around things people actually want. Items.

People love your games. People would love to buy upgrades to your games. We will make it possible for people to buy items that you create for your games - and you make the money.

SO it is sketchy and maybe untested but its interesting.
