Just finished tweaking around with the site. Wasn't altogether happy about how small and cramped the central post section was, so I've increased the width of it and the title bar. I forget the exact figures, but it feels less like a default 'blog' and more like an actual 'site' now.
I'm not sure how this will work on different resolutions - I'm about to try it now. If anyone out there ever bothers visiting this site, bear with me.
EDIT: Ok, tweaked it a little more and I've found a good compromise, I think. Now not only does it look much better then it did before, but it'll actually fit on 1204x768 resolutions. So to all my family members who are too cheap to pick up a decent monitor - you're welcome.
