You know, most of his comments--here and on other threads--indicate he doesn't fully grasp GTD. It seems he thinks GTD requires you must do things a certain way in order to be successful with it.
After 10 years of success with this system, I can't tell you of the number of ways I have customized, re-customized, morphed and changed over the years. There is nothing dogmatic about it at all. For GTDSuperman or whatever the troll is named to think so, only shows how shallow is understanding is.
But I think he'll be back. He won't be able to control himself. And I won't be feeding.
