Sad to say, this blog has been a victim of comment spam. I've changed some settings that should cut down on it, and I apologize for my oversight in not having it present from the beginning.
Cleaning up said spam turns up something weird: you can totally delete comments, but they still appear in the count when you look at the blog. When you click to see what comments there are, nothing show up! So, I apologize also for that misleading display, but I don't think I can do anything about it.
