I've been focused mostly on free apps with ads - mostly Admob - but the little control over what ads are displayed, their format, etc always seemed to bother me. That's why I've started working on an ad network for mobile apps - where the advertisers buys directly from the app publisher the ad spot - and the publisher has full control over which ad is displayed and when.

I wanted to ask you what monetisation strategies to you have for your apps and if you've ever felt the same way when you added ads in your app.
