I’ve been following Casey Johnston’s journey on Ars Technica to switch keyboard layouts from the ubiquitous Qwerty layout to the Dvorak layout with great interest and empathy. (part 1 and part2). About six years ago, I went through the same process to learn Dvorak. It took me five tries to succeed. Judging by the volume and passion of the comments in that series, keyboard layouts are a topic many people are pretty passionate about.
