yeah i figure i should learn a proper form but i'm dreading the unlearning stage, especially as the keyboard feels really cramped and awkward that way. maybe keyboards were designed for dainty women hands or something
I've never had any formal typing training and have developed my own method, I didn't look at the keys but I used 2-3 fingers only and it was pretty random. My typing speed was good enough (around 60 wpm) so even when I learned that there's a proper method for typing I didn't think it was worth it. However, I'm in a profession where I have to type a lot (computer programming), and my typing method was just impractical and properly not healthy for typing over extended periods. This is important, if I didn't have to type all the time then I suppose it doesn't really matter how you type.
This blog post was an inspiration as well.
Like you, I struggled with the unlearning phase, tried to look up articles that advocated against proper typing (they're all wrong), and tried to convince myself that it just wasn't worth the effort. But in the end that was just my laziness and frustration over the great drop in my typing speed and the apparent complexity of touch typing. After having forced myself to touch type for around two weeks I managed to reach a decent speed (40 wpm) and I'm still getting better. I can see why this method is more efficient than mine as it allows better utilization of your fingers, reduces stress on them, and also forces you to set in a proper posture. The only problem I still have is dealing with numbers and symbols, but I suppose you get used to that too.
I use both thumbs for the space bar but tend to use the left one more often.
Oh, and btw, a software that really really really helped me learn touch typing is
GNU Typist. It's a wonderful cross-platform command line application that teaches you proper typing using a lot of lessons and in a lot of languages. I've tried other software with GUIs but none of the free ones have as many exercises as GNU Typist.
