Previously Nathan Road used the (admittedly rather rudimentary) “Question posts” system on Tumblr to allow for user comments. The fact that absolutely nobody has posted any answers has not deterred efforts to tinker.

A Disqus system has now been cobbled together and will be fettled with over the next few days. It is currently set to allow users registered with Disqus or OpenID to comment without going through a moderator; unregistered users may comment, but their comments will be moderated before posting. (Out of distrust of Facebook’s privacy policies, Facebook Connect has not been implemented.)
