This blog's comments have always been hugely valuable, and some magnificent conversations have occurred in comment strings. I hate having to restrict them in any way (apart from the comment policy).
Sadly, this blog is now experiencing a comment-spam attack, and the "captcha" tool for verifying commenters appears to be useless. Our host, TypePad, can offer little assistance, and now and then makes things worse.
So two changes:
- Comments have been closed on some older posts that were attracting heavy spam.
- As of now you will have to register via any of a range of online identities, including Twitter, Facebook, and so on to comment.
If that doesn't work, we will probably begin (with regret) closing comments on all but the most recent posts.
Please keep commenting! Your comments have always been at least half the value of this blog.
