My schedule has been more than usually chopped up with non-blogging commitments lately, and I'm falling behind in thanking you for comments you've left here in recent days. I wanted to let you know that I appreciate them and will do my best to respond, when I can find a few free minutes. Wishing all of you a good weekend, too — one that will perhaps begin for U.S. readers of this blog tomorrow, given the Labor Day holiday . . . .
