I have just turned off the ability to comment anonymously on this blog. Over the last couple of days I've started getting comment Spam, so the system will now require a Google login or an OpenID login for comments.
I apologize for any inconvenience. If this is a problem for anyone (and I don't think it is, at least for those who leave the vast majority of the comments), please let me know.
I truly don't see the point of comment Spamming, but it appears it is now a fact of life here.
