A subject I have returned to a couple of times is how to use headings to make good document outlines in HTML documents. See Headings and document structure conclusions for a summary of my reasoning.
Recently I’ve been taking a closer look at how HTML5 changes the way document outlines are created. I’m not entirely sure that I have understood the specification fully, but if I have, I think the new outline algorithm requires you to think carefully when using the new sectioning elements (article, section, nav, and aside) if you also want a coherent document outline without untitled sections.
