Hooray for WordPress 1.5!
It was a completely painless upgrade experience, aided by some consise, clear instructions and the pre-flight that I did on my local mirror.
The new version is a very nice piece of software, and I look forward to take advantage of some of it's new features in the coming weeks and months. Fellow Wordpressers, do yaself a favour.
One of these features is the ability to mix'n'match themes for the appearance. At present you're seeing the girtby.net classic theme in all it's glory. If I can tear myself away from Half-Life 2, I'll flex my puny web design muscles and come up with something less ugly.
