I’m switching to Colemak. It’s an alternate keyboard layout that allows you to type while your fingers travel shorter distances. You can read more about the reasons this is better than QWERTY here: http://chetansurpur.com/blog/2012/11/colemak.html
My main reason for switching is that so many others at Automattic made the switch and had only good things to say. For me it came down to comfort, speed and the joy of trying something new.
I was considering the impact that this will have on my work as a programmer, but figured there will never be a good time to do this. There will always be deadlines, things to get done and communication to be had. So now is the best time.
Also, it’s time to try something new as QWERTY hasn’t done me much good. My current typing speed and accuracy is terrible and I experience pain in my wrists. I pathetically type 30wpm with 77% accuracy. My goal is 100wpm with at least 90% accuracy.
I hope to improve accuracy and typing speed and so my productivity and reduce fatigue in my fingers.
I’ll write more about my journey.
