We have two announcements to make to those who comment here:
First, if you are not already doing so, please consider seriously using your own name, rather than a pseudonym. While we do not, at this time, intend to make this a requirement, we do wish to strongly encourage the use of real names.
Second, a few people have sometimes written very long comments that really are essays in their own right, rather than being comments on the original article, or direct responses to previous comments. We have therefore decided to introduce a length limit of 400 words per comment, with immediate effect. Longer comments than that will in future quite probably not be published. If you still want to write such essays, we suggest that you set up your own blog, and you will be very welcome to then link to them in the comments here.
We hope that this will all lead to more and better comments.
