I’ve only met one other person that knew who/what Dvorak was/is, and also reportedly used that keyboard layout.
I experimented with it in University–I actually got a screwdriver and pried up and rearranged all of the keys on my keyboard within a week or so of starting–but after graduating I noticed that I was still slower at typing on Dvorak than I was on QWERTY so I gave up and changed back.
Yeah, I miss living in Australia where you didn’t have your own waiter but on the other hand that meant that it wasn’t rude to flag down any of the wait staff if you need anything rather than being restricted to having to go through a single person.
