I’ve just upgraded the blog to Movable Type 4.1, to make it more compatible with the post generation tool I use (ecto).
But for whatever reason, I can’t make the comments work. I’ve got a message on the Movable Type forums to see if there’s someone who can help, so I hope to have comments up soon!
Honestly, I’d rather move the whole blog to WordPress (which all of my other blogs are using), but I think that with the number of posts, comments and links I have, it would be a huge undertaking.
