Partly out of concern for my fingers, but mostly out of errant boredom, I have decided to try to learn Colemak. The QWERTY keyboard layout was intentionally designed to slow down typists, lest their typewriters jam. Now that computers have largely replaced typewriters, such a layout is inefficient, but we still use it anyway. Other layouts, such as the Dvorak Simplified Keyboard, just didn't catch on.
Colemak is another alternative layout that comes to me highly recommended. I can type 100-150 WPM in QWERTY, so why switch? My humourous little sidebar about shift key abuse is the symptom of an underlying problem; all these hours at the computer leave my fingers strained. A more ergonomic layout may be the solution. Besides, if I can type 100 WPM in a layout designed to slow me down, I should be able to type faster and more comfortably in a more efficient layout (once I master it, of course).
This was my first post (of hopefully many posts) composed using Colemak. It took a very long time, and I'm finding it frustrating, but that's expected. I haven't abandoned QWERTY, but the more I practice, the faster I'll learn. Wish me luck.
