Since you felt a need to mention me by name, let me distinguish myself a bit (oh, and I see Evan is here!).
I neither skimmed this system nor immedietely put it to doubt, so I don't know if I really fit well into your OP. I am there in a way that makes me appear cohesive with the other people you mention, when I am not.
When I first looked into the Enneagram, I was very taken with it, and at first thought I had something more valuable to me than the MBTI. Obviously that excitement drove me to consume as much material on it as I could. In doing so, I eventuallly lost some of my respect, as I found elements that did not seem to add up, elements that seemed devoid of a validation, and areas of concern that seemed to be holes, that is issues unaddressed, in the Enneagram. This did not happen over night, but it was gradual, and when one finds flaws in something he or she liked so much, the intelligent thing is not to suddenly throw it out, but to acknowledge the flaws and then, if possible, refine it. And so I began doing just that.
I want to know King, since I do not recall, did you participate in me and Evan's thread at all? If you did or did not, I have to ask how much of it you read? It is possible I have already said things there that would address questions and comments of yours here.
