Some time ago I saw an information about new StackOverflow section named Documentation. At the very beginning, I was very excited about this new feature. It sounds great to structure and organizes all the knowledge contained into this portal. Every day thousands of developers contribute to growing this one of the world’s biggest knowledge base. It is a great goal to achieve. However, when I started to look carefully at the content and the form of the knowledge in this documentation I realized that I even don’t know what good documentation means.
