Qwerty, Colemak, Dvorak, other?
Learning Colemak here and up to about 45 WPM average starting from about 20 WPM two weeks ago. Learning to touch type all over again is great fun and addictive . Passed the point of no return now, there's no going back to QWERTY I'm in too deep even though I was up to about 65 WPM average after being a lifetime looking at the keyboard typist.
The hard part is not learning the new layout it's forgetting the old one because you instinctively reach for the keys where they once were if you try to go too fast. For me around 40 WPM was the point where it stops being frustrating and it's all about improving the speed which comes automatically with practice.
I chose Colemak because the most common letters are all on the home row which means your fingers don't move as far so in theory it's less stressful and 40% more efficient than QWERTY according to research.
