As a result of Mark Pilgrim's excellent "accessible blog" series, and in particular, his Day 6: Choosing a DOCTYPE, I put the effort in tonight to make these pages valid HTML 4.01, with a DTD and everything. I'm hoping to follow along with the other suggestions in the series.

I like the goals of Mark's series, and I like the way he's going about it. As a developer, I appreciate guidelines like this that explain what to do, and what I'll get for the effort. The explanation of benefits is especially important in this case, because many of the benefits are either "invisible" (since they don't affect the rendering of the page that most of us see), or are only visible to a small set of people.
