What really helped me improve my typing speed is... switching my keyboard to Dvorak. Your typing speed will suffer for first month or so (assuming you practice during that time), and your QWERTY speed will never be as fast as it could have been, if your fingers constantly need to switch between Dvorak and QWERTY, but typing on a Dvorak keyboard will feel far more natural eventually and your speed will improve in the long term.
