A note on comments. I have been moderating them this past week, which is to say that I have had to approve each one before it was published to the blog itself. To date, I’ve rejected seven – three vitriolic ones from one of the people who persuaded me to shut comments off a month ago, two others that were off-topic put-downs of other contributors to the comments stream. And a couple by somebody who felt that their note should have been posted instantly to the blog and so sent it three times trying to see what was wrong. I’ve also gotten two emails from contributors about comments they thought I should have rejected. Significantly, each email concerned the other person.
