This is great, but would be even better if there was some way of logging in to save your progress! You're probably already working on it given what you write in your 'How to practice' page ;) but I'd love to have it track my progress and show a few basic charts. You could also gamify it a little bit (without doing too much) by adding a few achievements to unlock.

Edit: I like what http://10fastfingers.com/ does: really easy to get started, and an optional user account where you can see your progress (see http://10fastfingers.com/user/442112/ for mine)
