But if many thousands of webmasters remove AdSense and substitute "BingSense", believe me, we'll get their attention.
That's really what I have expected to happen since day 1. They told us to take a close look at our ad/content ratio, and that's what we're doing. The problem is, as people create new content or improve existing content, they aren't (as of yet) seeing any ranking improvement. So, the next rational course of action is to start removing ad units. Many of these sites that got hit are still doing well in Yahoo/Bing, so it seems to me that Google will ultimately lose on the Adsense revenue if they don't start letting some re-rankings take place. Webmasters are getting impatient. On the otherhand, E-how sits squarely in the top 5 for just about every possible query, and they run Adsense, so it's possible that it all comes out in the wash.
