Sorry folks but I've just killed the ability to post comments entirely. I love getting comments and carrying on conversations, but the 1000+ spam comments people try to post every month with a subject line of "respond this please" and spamming Viagra or essay writing or whatever was just too annoying. Even with the approval queue that made posting a comment require that I personally approve it before it posted to the site - and the captcha system - I was getting 1000+ of these every month.
It made it really hard to find the real comments. If you want to carry on a conversation with me catch me on Google+.
