I really like it David. When you first started this topic I didn't like the new site (which might have been just down to lack of "real" content), but as it's developed it's now looking much more pleasing.
My only slight niggle is the behaviour of the text when you try and highlight it. In both IE and Firefox it "shimmers" but it's not exactly a major problem.
When do you plan to launch?
It will be interesting to see if your SEO improves as a direct result of the valid code. Certainly the content DIV being read first by the spider should help.
