Yesterday I showed an educated Japanese woman Skritter. She told me she was studying Chinese so I let her try the app on my iTouch. She made so many mistakes that Skritter couldn't even recognize what she was trying to write. At first I thought there might have been a problem with Skritter, but then I flawlessly wrote a few characters from memory before it dawned on me that she didn't know the proper stroke order. It was insightful: I knew the stroke order better than she did.
What's funny, at least to me, is that I can't even read Japanese or Chinese! Skritter has endowed me with unconscious competence in low-level Chinese abilities but I am unequipped to handle routine tasks a child could perform.
