Qwerty vs. Dvorak smash-down
Fun blog entry at freakonomics summarizing the querty/dvorak debate. I love the way they summarize the different back-and-forth arguments. Sadly, they don't leave us with a ground truth: what's better?!
One thing not mentioned in this blog entry (though of course they well understand this point!) is that the economic argument for why querty won despite being inferior is not at all difficult: often the winning standard is one with market momentum, not the best technology. (e.g., beta vs. vhs).
