Interesting read, but I find comparing code to a map to simplistic. I would at least say that code is more like a puzzle of a map. You may or may not understand

Interesting read, but I find comparing code to a map to simplistic. I would at least say that code is more like a puzzle of a map. You may or may not understand each puzzle piece and where it fits it. That is my experience with reading code. Code is like Ogers and Ogers like Onions. They have layers of complexity :P
