Unfortunately, new comments on posts on this site have been suspended because of my illness.

Previously approved comments will remain visible.

I deeply appreciate the erudition and energy of our commenters. Your contributions to this site have been invaluable. But I can no longer devote the time necessary to separate good comments from the hundreds of spam comments submitted.

Because Wordpress weirdly doesn't allow me to simply turn off comments en masse, comment boxes will still appear at the foot of posts.
