I can be a fast typist, despite the fact that I rarely use anything besides my index fingers and thumbs, apart from a couple keys (such as the E and S keys, on which I sometimes use my middle finger). I never learned to "five-finger type", and my home keys may as well be WASD. However, I tend to be very methodical with my typing; I like to think about what I'm saying as I type, and I like to make sure that I don't make many mistakes, because I find that it's faster just to not make the mistakes in the first place than to go back and correct all of them.
