I’m often asked why I don’t allow comments on this site. The short and simple answer is that I just don’t have time to moderate them. There’s no way I could let them go unmoderated and so to keep up with them would be more than I could handle. That, together with comment spam and the fact that I would have to reply to any question/comment directed towards me (I can’t help it), would be too much. I might open the site up to discussion in the future, but I doubt it as I seem to be getting exponentially busier as the years march on.
