An Administrative Note

In response to some persistent comment spam, I have been forced to switch to comment moderation, which means that comments will not appear until I have approved them. I have no wish to stifle legitimate discussion on this site. Since I started this blog, I have deleted a handful of comments for profanity or bigoted comments. But I will not tolerate attempts to use my blog to sell term papers or even less savory personal services. I am sorry for the inconvenience to my readers. Keep coming back.
