Google AdSense: publishing stats

Google AdSense: publishing stats: "So Fred Wilson has openly published Adsense statistics on his site, including analysis of them.
And then John Battelle complains about the lack of transparency in AdSense publishing - not least the restrictions on not using other contextual advertising networks, or even discussing its figures.
Not sure these people have thought it through, though.
I guess the reason Google doesn't like discussion on AdSense at least involves the fact that, if the wider public learned which areas paid out most on clicks, then Google would be faced with a flood of low-quality websites on these areas - simply to display AdSense and try to cash-in on these clicks.
Google actually already has this problem - there are people in SEO who, in publishing across different topic areas, have already built sites to harvest higher paying AdSense clicks.
At least this is only a webmastering minority, though - and it's already a problem for Google's organic search, which so far as I can tell would rather push out the affiliate and advertising-only sites in lieu of the main content sites."
