I hope it will let people see tangible progress early, motivating them to really learn to code. I fear it will end up like fad diets, where early easy success gives a false impression that real work isn't required. I just did the Evernote API lesson now, and I made a note, and that's cool and all. But it taught me essentially zero about ruby or APIs or Evernote's API, and if I were to try to estimate a programming task as "Well, I used the api to make a note in about 10 minutes so obviously this other thing that sounds similar must be simple too" I would end up doing more harm than good. I really feel like opportunities to take a page-long tangent explaining concepts at every step should have been in the lesson. Even just links to wikipedia articles on programming concepts, something to provide the vocabulary - I think it would be hard for me to really learn more fundamentals based on this lesson because I wouldn't even know what terms to google.
