I've actually made some progress. By listening to podcasts at the same time as doing my typing progress, it's stopped being boring. I posted my typing goals about two months ago, but I wasn't actually able to stick to the thing until I found the podcast-typing combination.
I've been at it steadily now for almost two weeks. My touch-typing speed on the Dvorak keyboard layout is now at about 24 WPM. Progress!
As for the podcasts, I've mostly been listening to my Fiction 101 course by Randy Ingermanson. Before I didn't make enough use of them because of the boredom. Again, that typing and listening combination is really working for me.
