Matt Mower has resurrected his law on comments. As I just said to him in iChat I have made 1354 posts to my current version of The Obvious? and had 2118 comments. Anything that makes that balance less likely is a step backwards in my book.
I am still not entirely sure I understand the problem. Over five years of blogging and thousands more comments on my old blog I have had about five occasions (apart from spam) where I have had to delete comments because they were abusive or unpleasant in some way.
