Earlier this year I became interested enough in owning a keyboard that was better than my crappy rubberdome Logitech that was starting to be extremely mushy, so when the keys started to stick I decided to buy a mech - QFR with blues. It made typing become much more enjoyable, but it dawned on me that it would be even more enjoyable if I could type without my hands flying all over the keyboard. Also the keys were easier to press and required a longer stroke to actuate, so my previous hunt and peck accuracy fell somewhat dramatically. I had some spare time to put into typing, so I decided that it was time that I learn proper technique. Initially I was a bit unsure whether I would be able to retrain a habit that has become so ingrained in my muscle memory over the years, but I stuck with it, and in a couple of weeks I was up to 30-40wpm. I can now type upwards of 80wpm, but for the most part I still feel like something around 60-70 is far more comfortable. Having full command of a keyboard from a specified position is a great feeling.
I enjoyed the blues for a while, and the light actuation force and obvious click were nice to learn on. But eventually I started to develop an aversion to the loud clickiness of the blues, and as a heavy handed typist I thought the bottom out was quite harsh after long typing sessions. Also, when trying to gain in typing speed, I found that I was starting to mash the keys a little bit and it was messing with my typing rhythm. So I got an RF 87U 55g board, and while being much nicer to type on, I think I lost a little typing speed in the switch.
Technically I still don't know how to touch type. I started as a hunt and peck and slowly stopped looking and using more fingers. I have to cheat and look sometimes and I'm sure I have all kinds of bad habits. I don't do too poorly though and average about 70WPM.
This sounds a lot like my old method of typing. At one point (probably 10 years ago in Uni), I just realized that I could type with pretty high speed and accuracy without looking down, without ever previously putting much thought into it. Probably stemmed from all of those irc/IM convos. I have since learned to touch type (about 4 or 5 months ago), and I just tried to use my old method again and I notice that quite a bit of my finger combinations are the same as they are with proper touch typing.
I took typing classes in elementary school. So I think since age 10.
Same here. We had this typing program in the 4th-5th grade called Type to Learn with all these silly typing games.
Hah, same! The problem I had was that I just refused to take the lessons seriously, so I never developed the proper technique. I learned just to the point of being able to pass the class, but I never applied this way of typing outside of class.
I learned to touch type after I got my first computer. I think I was 11 going on 12, and I found my way onto IRC where typing fast became a game because we were all in so many different channels and private messages that I couldn't be looking down while other people were talking.
I didn't start following "home row" until I joined this forum though, and I think my speed increased more than it had in years because I focused on using all my fingers. My pinkies never really got any play before.
Yeah, I mainly use my pinky for shift and ctrl duties... I haven't gotten used to using them for normal typing yet...
I tried learning how to use the shift on the right side of the keyboard with my pinkie, but wasn't able to retrain my brain to do it quickly enough. It's incredibly hard to retrain yourself after years of doing one thing 
Before I learned how to touch type for real, I used to exclusively use the left shift, but I eventually figured out that this wasnt going to work anymore, and eventually tedious practice became habit. It was probably one of the more difficult bad habits I had to break.
