This is good news. Even with simple apps that aren't games he's making a decent amount of money off ads alone.

Too bad he didn't mention what ad network he's using. I'm getting ready to launch my game/app (http://developingthedream.blogspot.com/) in the next few months and I'm going into it with no expectations.

Good to hear i may gain a bit of extra cash from this project. I'm using mobclix and it was really easy to integrate into my app. However, I don't like that the view doesn't auto resize or fill the parent.
