Got email today from the Inside Adwords Blog that over the next few days they were going to be incorporating landing page quality scores and tweaking their algorithms throughout the Content Network (similar to what they did for Search this summer) Me, I'm all for it from both sides (AdWords and AdSense)
Could you give the text of that e-mail? From what you say about it, it isn't about how good the page is on which the ad is displayed, but about how good the landing page is to which the ad leads - so that would still be about adwords, not adsense.
