Comment You should probably stick with QWERTY, alas. (Score 1) 307
I agree with those who say don't bother with Dvorak. I taught myself Dvorak around 2000 until giving it up in 2004 (fighting with library computers throughout the intervening years). I might have been a little faster in my prime at Dvorak, but not much, and that training probably could have been better spent practicing QWERTY.
In theory, maybe Dvorak is faster for someone like you, whose typing is fast enough to challenge his max raw finger speed, because of reduced stretching for common letters. But I would say with the retraining there is *risk* -- learning a new layout kills your old muscle memory. Seems all too possible you might confuse your muscles, tangle up your pathways and never get to where you are at QWERTY, or back to where you were if you switched back.
It is true that the world's fastest English-language typist used Dvorak, however. Barbara Blackburn was a certified Guinness record holder, a Dvorak electric typewriter typist who once maxed out at 212 wpm, and for her efforts was once on Letterman. The Letterman segment is very silly: http://www.youtube.com/watch?v=NndiiezGkNY. NB, the days of the true specialist expert typists are past, alas.
If you think you are pretty good, check out video of Sean Wrona competing at SXSW in 2010. Seems like there is a little circuit where you can try out your stuff and maybe win a bit of cash.
