I feel the same way about what you have to say here. For the most part, I only use three fingers on each hand. (pinky and ring finger kind of float. I never use the ring finger for anything, but the pinkies are used for shift, ctrl, alt, enter, etc.) I spend a lot of time typing and have never had any kind of stress-related damage as a result. I tend to average around 90wpm - 140wpm with this technique depending on my level of intoxication.
I just took a typing test using the standard way of typing and only netted a score of about 45wpm. I taught myself to type before typing was offered in schools, so it is a bit odd.
