My android apps has quite successfully implemented monetization methods with maintaining positive User Experience. I think that now there is a time to share with you my knowledge. Few months ago I have started a blog Successful-apps.com | How to create great mobile solutions and recently I published an article about making money with mobile apps without hurting your users.
