That was my first thought too, but there actually might be something to it. The thing about man pages is that they require effort and force you to develop deeper understanding about the tools you use. From that perspective, it can actually be helpful to apps quality. I genuinely think that most of web developers now (myself included) got used to solving problems by quick and dirty means. Our whole development process seems to be based on piling technical debt until we can't figure out what's going on. I'm not actively encouraging using this stack for development, but as a wake up call it's not without merit.
