Improved commenting

The Intense Debate comment system is the most sophisticated that I’ve seen – allowing for nested commentaries – and we’ve implemented it here. If there are problems with the integration, I’ve not found them yet. The comment widget on the sidebar might not update properly and this will be a work in progress. If you see troubles be sure to let us know. (If you are moderated, we can assure you that it is inadvertent and a matter of software tuning.)
