Question [Q] The experience working with Ad Network as a developer?

I currently have about 15 apps in the Android market - some moderately popular. All said I have a total of over 2.5 million downloads.

I tried Airpush in one of my apps. My app got a lot of 1 star comments saying things like "Shows horrible ads in your notification tray!", People don't read the app description. They just download, then complain. Also the eCPM seems not good enough. Someone can help me?
