Don't get me wrong, I used to write as semantic HTML as I could; nav for navigations, table for table's, aside for well asides, etc as the author suggests, but ultimately it just really doesn't matter. nav and div render exactly the same. In fact, I find zero value in using ul/li's for lists that aren't bulleted. I know it's an unordered list of items, but really, what _is_ the value in writing semantic HTML if the devs/browser/users don't care or know the difference? Especially if you're changing the "semantic" element's default behavior in order to get a look and feel or behavior that is far from the original "semantic" intent.
