I think my top four list of things that people who are making blog posts should know are:
1. What you said about descriptive link text. The importance of descriptive link text is huge. 2. Trying to be clever with link names, style text, etc., can make your page less accessible. 3. When you are making interesting layouts (less likely on a blog post, although you might do it on a style), use CSS instead of tables to lay things out. Really. I know people disbelieve that it matters but it really really does. 4. If you are conveying any information solely via color, formatting, image, or flash, make sure there is an alternative way of getting that information. If you are conveying navigation solely through one of those methods, make sure there is an alternative way to navigate.
