On rare occasions, a comment posted here may not appear because it is mistakenly flagged as spam by filtering software (which, otherwise, does a fine job keeping junk comments from appearing.) Very long comments, or those with lots of links, are more likely to register as false positives. If you do post a comment and it does not appear, please email me and I’ll look into it: it’s usually straightforward to rescue the comment from the spam heap. Thanks.
