Jo reminded me on the phone that this site is currently messy in Microsoft’s favourite son. Since this design is going to stick around rather longer than I once planned, consider this a commitment to hack it into shape in a few weeks time.
In related news, Google Analytics reckons I’ve only got 35% IE usage visiting the site, with ~50% using Firefox and a whopping 10% using Safari. I guess the low IE usage is quite likely linked to the aforementioned brokenness, though.
