I just type how I want. I don't have to look at the keyboard but it's not because I use touch typing-- it's more like I just have good spatial memory because I've been using computers for so long. We had to learn the proper way to type in like 5th grade but I was waaay ahead of everyone else and I just typed my own way.
This.
Really (and you guys are going to laugh at this), I learned how to type by playing EverQuest enough...I mean, all that communicating, and you've got to learn how to type and to type well. I never use home row, never have any discomfort, and still type on average about 100 wpm with near-perfect accuracy (and if I make a mistake I usually realize it while I'm typing, and just use backspace as if it were another letter in the word).
I don't think I'm any sort of KEYBOARDING PRODIGY, I just think that the more you need to communicate via typing, the faster and more accurate you will be. One really helpful exercise is to type on an "air keyboard." You know, like air guitar...but it's a keyboard. Type sentences on it, and if you can find every letter on the keyboard, you are well on your way to mastering typing. No Mavis Beacon required (although it was kind of fun as a game, back when it was just plain ol' "Mavis Beacon Teaches Typing, v1.0 lol).
