Seibel's observation that reading code is less like literature and more like science is dead on. No matter how readable the code is, when I'm confronted with 10,000 lines of it spread across numerous encapsulated functions, I must tackle it very differently from how I read prose. With a complex literary text, I can just read it in linear fashion with occasional segueing to look up words and concepts, with well-engineered code I must follow numerous cases into different flows of logic. These aren't the same at all.

I appreciate that he's trying to dispel the idea that we "read" code as we read for pleasure, I learn from code by experimenting with it. I open up the debugger and step through it, watch the variables change and see where it goes when I execute it. Most of all, I learn by changing that code and trying to build on it. I have enhanced my javascript skills immensely in recent years by cloning various projects on github and trying to expand on them or adopt them to my own purposes. I don't recommend opening up a code base and just reading it, actively engage it, break it, and enhance it.
