When I was in high school, I used to be able to pull off 150 wpm. I used to play a lot of text based games (MUDs) at the time
(yay for Aardwolf). Anyway, I've since dropped down to around 80 wpm.
Funny thing is that I don't "touch type"....my hands hover all over the keyboard. I call my kind of typing as "common typing", where when I'm typing words I'm familiar with (such as common chat talk), then I blaze through those easily at +100 wpm...but when I come to a word I am less familiar with, I slow down to around ~60 wpm.
I've seen people's funny reactions who watched me typing....they're like "you hands are all over the keyboard...how the hell do you know what key you are hitting?"
