Google Launches AdSense

Today, Google launched Google AdSense. Its a service that allows content publishers to serve Google AdWords on their own websites, and receive part of the pay-per-click. How much, you ask? Well, unfortunately, this program doesn't seem very well thought out or developed:

1. How much will I earn through this program? The AdWords ads you are able to display on your content pages are cost-per-click (CPC) ads. This means that advertisers pay only when users click on ads. You'll receive a portion of the amount paid for clicks on AdWords ads on your website. Although we don't disclose the exact revenue share, our goal is to enable publishers to make as much or more than they could with other advertising networks. (Emphasis, mine.)
