I've completed the migration to Moveable Type. I've checked the pages look ok in IE6, Mozilla, and Opera (the About page required a minor tweak for it to look the same in Opera). The old Blogger archives are still available and can be accessed via existing permalinks. I've added the XML and RDF icons.

The one outstanding problem is that MT strips HTML tags out of entries when generating RSS files, which means that entries which contain formatted text, for example code sample, are not very readable.
