I think this is a nice challenge. Touch typing was something i was never taught. I definitely have incorrect finger placement for instance.

However I know my overall typing speed is good from the 20 years i've spent behind a keyboard! I actually think the UI is good, with some interesting elements that are not so distracting.

IMO, finger placement is a total red herring. I can type around 170 WPM (if exerting myself - and assuming typeracer.com has accurate WPM scores) without looking at the keyboard and I've never once used anything close to the prescribed "touch typing" finger placement taught in schools. Whatever works works.
