A shout-out to Jim Chen

Thanks go to Jim Chen, who, when he isn't deaning, is walking a Luddite like me through the basics of blogging. I've now gone back to an unmoderated setting on this blog. Jim taught me how to delete junk posting. I won't delete the comments that are relevant, even if I disagree with them--just the ones that are truly the equivalent of junk mail. That will in turn, though, cut the number of comments that I get at all by a significant amount.
