In preparation for a Movable Type upgrade, I have changed all the URLs for the individual entry and archive pages. Old links are being autoforwarded to the new URLs, so don’t worry about that. But this change will probably cause your RSS newsreader or aggregator to mark old entries as new again (James is going to kill me for that). I’m doing it to address some version incompatibility issues; it will be better in the long run.
Meanwhile, there appears to be some high load issues going on with my server at the moment. I’m investigating.
