I really dislike the thesis of this article. It implies that upper management SHOULD make decisions about technical matters based upon what someone wears. This is almost a guarantee of wrong decisions. When I see someone dressed non-traditionally in that sort of environment I think there's a guy who expects to be judged on the merits of his vision, knowledge and skills. This article should have lectured non-technical managers about what to expect of their most valuable people and not the other way around.
