And one last thought. Can anyone disintermediate Google? From what I can tell and what I've read, Adsense apparently gives publishers about 30% of the revenue per click, while Google takes 70%. AdBrite is interesting, but it's just not as easy to use nor does it have the variety of high quality advertisers as AdSense. How many quality advertisers do you have to have in an ad network before publishers will switch from AdSense to you?
