Maybe because 1994 had something right-- his pages load VERY quickly, are dense with interesting information, and display sensible in all browsers; you can't say that about the vast majority of the modern web.
Must've hit a sore spot or something...
Even without a degree in design one can see that this page is nearly unreadable. The easiest (but not the only) thing to fix is to limit the width of the column of text.
Why limit the width of the text? If I want it wider, I'll make it wider; if I want it narrower, I'll make it narrower. This is something I can do with a relatively plain text webpage.
Edit: Although I see sdiq below had a browser that apparently couldn't handle plain HTML without help from him. Perhaps something in your browser is making it unreadable.
You can resize your window to whatever size you want.
