I don’t pre-moderate comments, but on topic comments are always preferable. If you wish to broaden the context of a discussion that is OK, but please if you simply want to move it on to particular hobby horses of yours please do it elsewhere.

If you are going to make a factual claim please try to provide a link, or reference, so that it can be checked.

If you want to respond to a blog post, please do it here and not on Twitter. Twitter’s largely a two way discussion. Put your comment here and might persuade more than just me.

I’m not a huge fan of anonymity. We all have real names, so please use them.
