So I just thought I'd mention that pmk is totally nuts. He's applied a genetic algo against keyboard layout, and apparently come up with something that is "close to dvorak". While I'm not big into modifying my keymaps (I tried dvorak for a few days and finally gave up... too lazy to get used to it, I'm afraid), who knows. Maybe you are.

It's a damn cool idea, though. Those wacky Cray hackers...
