Well, the fruits of my modest labour are now online. I'm fairly pleased with the results, considering I'm anything but a designer. The best effect is gotten on Windows 7+, because it uses Segoe UI and Segoe UI Light (it still looks okay if those aren't available though).
Only the home page and blog have been updated (I plan to do the other pages later).
As I said before, it's all MVC4 and uses jQuery, Foundation, and a little bit of Knockout (though most of that is in the admin pages which you can't see, obviously). I've tested it in IE9 and 10, Firefox, Chrome, Opera, Safari on iOS, and IE10 on WP8. I'm pretty pleased with how nice the site works in the mobile browsers thanks to the responsive layout (a few warts notwithstanding, particularly recaptcha is just a bit too wide).
On IE8 and older, it's not such a nice story. Foundation defaults to "mobile-first", which means they get a one column view regardless of screen resolution. That wouldn't be an issue, except that means the top bar menu defaults to collapsed and cannot be opened due to script errors. So while the content is reachable, it's a * to navigate without the menu. But frankly, I don't really care about those old browsers anyway. Just upgrade already.
