This blog has no comment-publishing facility: it's all done by hand. Feedback is welcome, though: if you would like to get in touch, email me on comment2010 @ telent . net and I will publish your thoughts (unless you tell me you don't want me to) as an addendum to the article, provided only that in my view they are interesting, amusing, relevant, accurate, or (best) some combination of the four. Relevant links are welcome in support of your argument: spam and untargeted requests for help are not.
