Haloscan commenting is now available at the bottom of each post.
When I started this blog, I used a newly-available commenting system called TheirSay. TheirSay has proved consistently unreliable. It is operated by a right-wing Canadian called Andrew Coyne as a pet project. I removed the TheirSay commenting aabout two months ago, but couldn't get the Haloscan commenting working for some reason. After leaving it alone for a month, I went back and looked afresh at the code and saw the problem immediately, so now commenting is up. Please note that I can and will ban you from commenting if you troll this blog. No serious engagement will be banned however.
