At Eliot’s request, I changed the way comment-posting errors are handled. In addition to an error message (which I agree could probably be more helpful) the site will now give you a new form pre-populated with the text of your comment so you can try again. I’ve tried to test it but there might still be some minor glitches – particularly in how quotes and backslashes are handled.

Good luck, enjoy, and keep posting those comments. I get a kick out of knowing that what I write actually interests people enough for them to respond.
