Great read. This sentence sums it up best I think, "Why, why, why would people expect to get great results if they flaunt all the best-practices that have developed over the past 20 years?"
I don't think he's using the word "flaunt" correctly. It struck me as off -- sure enough, the definition agrees with me. "Flaunt: to parade or display... conspicuously. The use of 'flaunt' to mean 'to ignore or treat with disdain' is strongly objected to by many usage guides.'" http://dictionary.reference.com/browse/Flaunt
flout (verb) 1. openly disregard (a rule, law or convention).
