First of all, it's clear that the article is not talking about the QWERTY layout per se, but the character set on the keyboard-- switching to Dvorak would do nothing to improve the situation described. Second, it's odd that he doesn't bring up the experience of APL, the only language that I know of that tried to break out of the traditional character set. Aficionados find it concise and elegant; personally, I find it cryptic. I fear the same might occur with other attempts in this vein.
