Your outlook on this really depends on subjective definitions of "truth", "understanding", and "alone". I realize it's one of the central hypotheses of the article that side projects need to have a social component - but whether that's true is entirely dependent on someone's personality. The overwhelming majority of side projects will never get shared with anyone, and I differ with the article in saying that's not a failure which needs to be corrected. On the other hand, there are side projects that happen with many people collaborating from the get-go; however, I would be hesitant to declare this a globally ideal format for all programmers doing hobby hacking.
