Relax with the vitriol. The guy is sharing an interesting personal story, not providing a step-by-step HOWTO or recommending people follow his suit. In fact, the article is really an ad for his startup Courseware.
CourseTalk. CourseTalk! http://coursetalk.org .. You are right kind of :) But I've made a decision to start reaching out generally so I can attract cool people to work with on whatever projects I may be interested in in the future.
By the way, no offense meant by the advertising thing. I enjoyed the article. Although, as a technical person, would've enjoyed more details on the code and algorithms.
