This article does not sound like "users" to me. They more sound like ex-managers of the author. Two totally different sets of people. "Managers from Hell" is a more appropriate title. But even so, I wonder how much of these supposed "stereotypes" are just the rantings of a disgruntled employee? I am not saying that these type of people do not exist in IT field. They exist in "all" types of fields, not just the IT field. Like my father used to say "You can either analyze life, or just live it and deal with it." People will be people, and you can't change what you can't control. So, don't let this kind of "stuff" rent too much space in your head.
