The point of the ads is not to replace adsense, but to have people use us along with adsense. Would any of you guys use this?
However, I would take a little more time to review the text on the pages. There were a number of phrases that struck me as... infelicitous. Most notably: "Each time somebody sees the ads on you site, a partner site will be display your ad."
Those little blurbs are the first impression people get from the service, and the difference between sounding like "just some random site" and "a really cool, professional ad service" will make a difference in adoption rates. Best of luck!
In the future you will be able to choose the ads you want to display based on keywords and categories. Right now though, we wanted to make it as simple as possible (with the least amount of steps to get it set up) so it's automatic.
