I started this year by laying out a step-by-step strategy for how to transform publishing in the age of the iPad. My January article "iDiots' Guide to Publishing on the iPad" was a hit on Twitter. Boy, was I wrong. I dished out a ton of advice, offered specific suggestions about how publishers should cross the chasm to digital publishing, how to engage their readers, and how they should productize it. For all my good ideas, I fell short by missing the most important element: the hardest thing in the world to change is human nature.
