I don't think that you really have to be, I think it helps less than in regular writing.
Personally my style is very anti touch, using 2 fingers for the majority of letters, which I don't have to look at the keyboard for but I probably take more glances at it that a touch typist. I think though in being proficient in navigating the symbols on the keyboard mostly makes up for the loss in outright English typing speed.
