Oh yes. I run a image hosting service and adsense cant serve any relevant ads because the page hardly contains any text. The only text they identify is 'image hosting' and start serving ads to competitors T_T. My service has more information about user interest though based on topics and other user interactions etc but there is no way to forward these hints to adsense :( Any tips on ad providers that support more explicit choice of topic per page load?
