There are many comments I get that, while not necessarily being disrespectful or mean-spirited, nonetheless add little value, are egregiously wrong and ignorant, and would waste a lot of my time and energy to address. Fortunately, many of them are by first-time commenters and get caught by the moderation filter. I have deliberately left many of those comments there. While I’m not certain whether or not that’s fair or wise, it has been expedient. For now, I will continue to do so, and institute a de facto policy of denying hopelessly stupid comments from getting through. If you have a comment that’s been sitting in moderation for a long time, that’s why.
