This is hardly a new idea. The fact that a bad programmer used Ruby on Rails, or Django, or PHP, or C++ to write bad code and implement it on a shoddy system is no reflection on anything. This is essentially a story of someone who took good advice for a hosting environment, and someone who took bad advice for a hosting environment.
Learn your tool, don't buy into the hype. Make sure you are aware of the reason behind everything that you do (because they I read it on a blog is not a reason). Don't be a bad programmer.
