Keep in mind that you can make the information at that site 1000% more readable by changing your browser's default web page font to something like Tahoma. Sometimes it can also help to use a "skinny" browser window to narrow the width of long runs of columnar text.

The Web has conditioned us away from real reading, instead looking for the quick gratification of a code snippet we can paste into place. Many Web pages are a travesty, with 400 words of actual content embedded somewhere in the cracks between acres of Flash ads and other nonsense. The one linked above doesn't have these problems.

Anything we can do to improve the reading experience is good. You can pick up a great deal more depth by reading what people took the trouble to write instead of pasting in code and hoping it works in the absence of understanding.
