Is this thing on?
Grrr. My apologies, but I only today learned that an incorrect setting on this blog has rendered comments all but inoperable. I'm not sure how long this problem has existed. But the last comment was logged on March 21, and even given that I was out of town for almost a week between then and now, the commenting dry spell should have tipped me off before now.
Again, I apologize, and for anyone who has been trying to comment, you are now free to do so. I think. (If you run into problems, please e-mail me and let me know. Thanks!)
