Google gives permission to some sites to do more. we are one of those sites.
There's obviously a reverse incentive at play here which stinks (IMHO). If you make the page useful to users, they wouldn't click on any of the ads. So it's in your best interest to create bare minimum pages, or pages that give the users a token amount of value - the bare minimum.
I'm surprised at Google for allowing this sort of thing and specifically allowing you to put even more ads up than is usually allowed.
