Decent article, although I really could have just skipped to the "Configuration" section and started reading there. One thing is I'm sad this doesn't accounting for actual physical keyboards instead of letters on a square grid. D to R is much closer than D to W, for example (on a standard qwerty keyboard, typical row slant).
