Comment spam is overrunning the blog and I've had to shut comments off. My apologies.
Obviously, I'm far overdue for upgrading this blog to new software that isn't so inviting to spammers. I don't post that often and may not bother--but if I decide to start a new blog on a less spam-ridden platform, I'll post a note here. (Assuming I wind up needing to change my domain or something.)
