With enough time and effort, anyone can write code that adheres to some coding guideline. Meanwhile a disproportionate amount of developers struggle to provide practical, concise documentation of their code. I don't want to dive into Mr Clean's legacy code to find out how to call the stuff needed to develop some feature because he's too smart to write it down somewhere. I'd rather have a more informal codebase where the developers have taken the time to explain what each relevant thing does and the quirks of each non trivial function.
