In addition to the many useful tips here, I'd like to suggest that most pages should have a "first presented" or "last updated" date. Some pages should have both. This can be in some "cheap" real-estate - maybe near the footer. While reading your site, I was surprised to find references to the new Netscape 1.1 browser, for example. I just graduated from using the 6.0 version to Mozilla. Particularly, with advice and howto pages, I really value a quick hint at how current the data is likely to be. I don't necessarily depart old pages, I just make sense of them more quickly.
