PG has addressed the issue of HN's markup several times. One of the major advantages of CSS, that sitewide changes can be made in one place doesn't really apply to HN. All the HTML is generated by Arc code which is written in a reasonably DRY style; major changes can be made in a central place.
I like modern markup and layout better than the way things used to be just like almost everyone else, but It's hard to come up with an argument for switching HN to more modern markup. It wouldn't make the site easier for PG to maintain, and it probably wouldn't result in a change to the visual design unless a designer was brought in.
