This is the type of article that really gets my adrenaline pumping. I find it so frustrating to read about these types of things, although the frustration for me is in the fact that people take one person and vastly over generalize to an entire class of people. Yes, there are "Certified DBA's" who are morons. Guess what, there are System Admins that are morons, Programmers that are morons, Pilots that are morons, Doctors that are morons, etc, etc. If his main takeaway from that situation was that "Certified DBA's" are morons and that system tuning is little more than hand waving and hot air, he failed to learn the real lesson. The real lesson imo, is that in every field you have people that are morons, and you don't know if the person you are dealing with is a moron based on their credentials. You only know if someone is smart and gets things done through actual experience. For what it's worth, performance recommendations of this sort are the easiest to expose because of the availability of quantitative performance measures.
