The fact that Michael's response (see below) had to be emailed to me and then posted, instead of being put up as a comment is just more evidence of the damage that the spammers have wrought on all of us. Why are comments off on that post? Because I tend not to notice comments on posts once they fall out of the RSS feed, and I used to get spam in such posts. Sure, I could have comments emailed to me so that I could verify them - but I really don't need the extra email traffic. Just one more sign of the eroding commons...
