Well, I put up with it as long as I could. I believe that one should have open comments on a blog about being open.
But the spammers have worn me out with the deleting of the spam posts.
I have set the blog for comment moderation, at least until Google gets a better way to filter spam posts. I apologize to anyone in advance who thinks that this contravenes the concept of being open. I promise all non-spam posts will get posted.
