On a housekeeping note:
* Comments - thank you for your comments, they're ALWAYS appreciated, as are trackbacks. However, because of the prevalence of spam, comments are still moderated, that is, they don't go live until I read them. Spam has slowed down, but there's too much of it, so it means that comments need to be moderated or the blog would turn into a pharma-advertising wasteland;
* The RSS feeds are now set to excerpts only, because of content theft.
I know that comment-moderation and trimmed RSS feeds make reading this blog harder than it should be, and I'm sorry for that. I hope you'll bear with the hassles until karma catches up with spammers and scammers. Of course, this may not be in this lifetime. :-)
