Blog move

It was both easier and harder than I anticipated to move the blog. Easier because the WordPress software did a lot of the work for me, harder because I didn’t realize that WordPress did most of the work for me, and I ended up making some of the changes prematurely. Fortunately, I have backups — and I’m a fairly resourceful programmer, so I was able to find all of the remaining places that I needed to run some SQL updates, and managed to come back up reasonably quickly once I figured out what WordPress had already done.
