Due to the recent rise of non-comments that are essentially comment spam I am now enforcing some level of comment moderation. If you are a first time commenter now then your comment will need approval and I will be much stricter on the spam comments.
If your comment is not interesting or constructive it may well disappear. I do want to encourage conversation on this blog, and as the comment count edges towards 5000 I feel that it has been accomplished, but recently I think comment spam has become a problem.

Comment Policy
When posting comments please use your name or your initials, please do not use your company name. Please don't link to your company name in the comment text either. This will be considered spam, and will be deleted. Opinion of any kind is welcome, but any personal attacks will also be deleted.
