Well... I suppose it's technically more efficient to use home row and all that, but I took a typing class in junior high and quickly realized that I was more effective, faster, and made less errors if I was only using my patented hunt-and-peck method. As it stands right now, I very rarely look down at the keyboard when I type and I'm clocking around 75 WPM, if my previous place of employment is to be believed. I use whatever finger happens to be in an ideal place on the keyboard at the time. I'm not sure if there's a rhyme or reason behind it, but it works well for me because I can do... well, thing of it like a musical progression. Every finger is in a place for me that I'm faster and more efficient, and I have greater range of movement, whereas using the "proper" technique slows me down and screws me up, as well as restricts my mobility.
Of course, the way I described all that sounds like the reasoning behind using touch-type (I too have never heard that term), and I suppose if I used the correct method I wouldn't type so damn loud, but I'm quick and I spell correctly, so I'll be damned if I'm going to change now.
