What’s embarrassing about initiating a little reader participation? Your question illicited a response which uncovered information about a guest stint.
The embarrassment might be in the brevity of the entry that doesn’t mention the book being reviewed (‘The Din in the Head: Essays,’ by Cynthia Ozick) — makes it more difficult to find the entry in a search of relevant commentary on the Kirn piece “The Canon as Cannon”.
The embarassment probably stems from the links-without-context nature of the entry. It is far removed from your usual posting style which is sensitive to the modes of narration.
BTW, what book did you (do you) want to send Kirn?
