I don't know why, but I found it slightly offending that you called not using the home keys "sloppily". But.. Then I realized you're right. My style is definitely sloppy..

I wanted to learn touch typing properly, so I took a touch typing class in high school. But it wasn't a very good class and the teacher basically told me I didn't have to do anything to pass as I already typed 30-40 wpm faster than anyone else in the class... Guess she didn't know proper touch typing either

My hands fly everywhere on the keyboard when I type. I honestly think this might be better for minimizing RSI, as I switch between using different muscles for movement. There's really no system behind it

I once got told it looked like I was torturing my keyboard, not typing on it.
