THE single most significant factor, for me, in all of this is that hardly anyone uses my responsive mobile sites, insofar as AdSense is concerned these sites have earned ZERO in 2012!

I'm confused, are you assuming that nobody uses the responsive mobile sites BECAUSE they don't click on ads? Or am I reading that wrong?
