My tip to improve your typing speed is to... If you are typing 60 wpm or higher, and want to get better, and not get carpal tunnel: buy a mechanical keyboard. I use red switch that I bought for both gaming/typing, and after an hour of typing, my fingers still feel fine. I wouldn't recommend red for most typists--It doesn't have the feedback that other switch types have, and takes a while to get used to not bottoming out the keys all the time.
