I have been looking into the complaints about missing comments and the error was mine. They were simply held up in my spam filter. Please accept my apologies. As a long-standing user of the Typepad platform, I should have been better aware of how it works.

Please click on the email link in the sidebar to let me know if you have such problems in future.  I promise that I will liberate your words of wisdom as rapidly as I can. I shall also be checking the filter every 48 hours.
