Very nice. Your article made me want to read the entire book.
Nice, but what's up with the random capitalization of words (example: "Developers ARE happier AND MORE productive WHEN USING the tools they ARE most familiar WITH."). I stopped reading after struggling through the first few items.
Sorry about that. Now it is fixed (at least most of them). I had to do some automatic updates of the underlying wordpress database and I guess that one of them messed the capitalization. I'll need to explore what happened in more detail.
