great idea IncrediBill.
for a few years i personally felt i worked for Google "not for my visitors". a lot of my time revolved around Adsense and optimizing for Adsense, and SEO for Google. I even neglected great features that would have helped my users because of their negative SEO/Adsense impacts.
I've been slowing phrasing out Adsense in place of affiliate offers and direct ad placements, and to date I earn around 5 time more from my other sources then Adsense.
I still use Adsense and love it, but honestly i see Adsense as a starter monetizing system, until you reach a point where you can command your own value, and direct your own placement,and look and feel, etc.
could you imagine if facebook was monitized by adsense?
