So you switched back to QWERTY, and/or now type Colemak, I take it?

Nope. I still type Dvorak. One switch is enough.

I can type QWERTY, too. If I use a different machine, I'm able to switch over with surprisingly few errors. Also, strangely, I can't tell you where the keys are on a Dvorak layout without mentally typing the letter. I used to know the QWERTY layout by heart, but never reached the same level of mental mastery with Dvorak.

The only reason I suggest Colemak is that I've heard it's optimal for programming. I still don't think it's worth learning, though, if you already touch-type QWERTY.

My understanding is that Colemak isn't any more effective than Dvorak; it's just closer to Qwerty, which makes it easier to learn up-front.

But honestly once you get away from Qwerty there's a law of diminishing returns. The differences between non-Qwerty layouts are pretty miniscule compared to the difference between Qwerty and good layouts.
