After 5 years of Dvorak, I am switching back to Qwerty.

In 2012 I, with two other nerdy roommates, switched to Dvorak. Five years later (four of them spent as a Software Engineer) I am switching back to Qwerty. In fact, I am struggling at 30 WPM (a 70% reduction in speed) to write this post now.

The Dvorak Simplified Keyboard, patented in 1936

Why did I switch in the first place?
