Wow! What an awesome critique. I'm in awe. First off, rather than just saying Khan Academy missed the point, Mr. Victor goes over in extreme detail with full examples with ideas on how to do it better. Second, he really went into some detail about how to think about things. Not just the solutions but ideas and ways of thinking to come up with better solutions. Third, he's set the bar for critiques higher than I've ever seen. Next time I want to critique something I'm going to feel at least some responsibility to give good and clear examples of both what I think is wrong and what I think would be better with reasons. Fourth, even if I never write software to help learning programming or help programming advance in general I'll certainly be influenced in my API and system designs by this post. Thank you Mr. Victor
