Sorry blog fans, but we had to go back to comment moderation, and I highly doubt we'll ever return to open commenting after this latest episode. We tried to open up the floor because John was away, and because this blog is by far our most popular in terms of comments, but we couldn't even do that for a couple hours without the blog degenerating into a childish display. Sometimes it's hard to believe adults can act this way, but it is what it is. For the people who want a civil discussion and yes, even civil debate, I apologize for the move, and for having to read through personal attacks that are nothing other than a waste of your time. A few bad apples have spoiled the whole bunch.
