CODEHACK: Codecademy's "Code Year" initiative, with over 340k signups so far, promises that "you'll be building apps and websites before you know it." Coding manual author Julie Meloni thoroughly warns against such delusions of grandeur, asserting "teaching through imitation without context or mentorship" and rewarding with badges are simply not useful pedagogy. (EdSurge's Tony has signed up, and feels like he's been doing a series of search and replace problems. A more fitting description, he thinks, would be learning how to hack.)
