Google? Why does Adsense make no sense (or do I mean cents)?

One of my biggest frustrations with developing software and distributing it for free is that I don't receive much feedback. Occasionally, I get a nugget, but more times than not, people download Book Me and that is the last I hear from them. If you download Book Me, please tell me what you think. If you like it tell me. If you don't like it tell me. Those of you that visit my site are not clicking on the ads that show up in the sidebars. That leads me to believe that putting Adsense ads on my blogs may just be cluttering it up. I am seriously thinking about pulling them off. Sometime I wonder if they even work the way Google claims they do. Google Gods, I am growing weary. Show me the money...
