I agree with avoiding "authoritarian" comments. The closing system has much guidance
built into it that aims to be fair but terse; there's no reason to duplicate that (badly) in rote commentary. Which to me suggests that
if you can't improve on what the system is already saying, don't leave any comment at all - an awful lot of folks seem to comment because they can't resist saying
something, even if it's unhelpful; saccharine nothings aren't making the site friendly either. If you have specific insight into how to improve the question, edit or comment... Else, vote and
walk away. —
