I've moved blogging platforms. As it turns out, automatically moving content from Typepad to just about anything else is really hard, so I'll be manually bringing over some of the blog's history as time permits.
Sorry for the ignominious end to 10+ years of posts.
UPDATE: Who am I kidding? I'm not going to find the time to move over selected posts from the old blog. They can be found on Typepad at: http://cwirving.typepad.com/
