Given the polite (lashon-hara free) tone of the discussion, we have seen no reason to moderate comments. The blogger policy we have invoked is that comments are posted immediately (I hope we can continue to do this). However, comments go to the moderation queue after 14 days. We just noticed some comments in that queue and have enabled them (but this is an error prone process as someone has to remember to look at the queue). Please provide us with feedback on this policy.
