The reason this warrants a blog post is that part of this change required me to kill all of your comments. I have a backup of the comment database, but it looks like a reasonable amount of quite boring work to transfer those comments into Disqus, so I might simply not bother. This blog is young enough that the absence of the comments on the older posts won’t really matter too much. Everyone gets a clean slate!
I promise, a real blog post will come a bit later, when the weather gets worse and I’m less inclined to be out in it.
