I have students that have been programming (in Java) for two years and have coded simple arcade games from scratch. These same students will spend more than five minutes unsuccessfully trying to get a single CodeCademy exercise to work. (I don't mean lesson or section: I mean a single page.) Some of the "tutorials" are so poorly written that it's just completely unclear what the author wants the student to do. I can't imagine that a student with no programming experience and no mentor is having a fun experience.
