See for yourself, and when you click on the see comments section you get the Amazon can't find this page, which is what happens when a review with comments has been deleted. This topic has just been raised on the discussion boards. Of course, that doesn't appear to be a problem with the review comments that are flattering to him :-)
As a refresher on this, pick any old review of yours and post a comment. Delete the review and repost it. When you look at all your reviews it will still be in the same date, but with the comment gone. However, if you change the option under reviews to see by newest comment first, you'll see that old review still there showing a comment. Click on that you should get that lost page message from Amazon.
