These are interesting questions, but I have to put on my consulting engineer hat and ask, "What problem are you trying to solve with all of that extra stuff?"
The pages are plain because we're discussing and solving technical questions. We can do that without graphics or gorgeous CSS, so there's no need to add it. Yes, the look of the site may date it to the year 2000; however, the site is functional, and full of excellent reference material.
