And curiously, right after posting this, my comment and the one I responded to have reappeared.  Perhaps monitoring of comments is improving.  

Civil Comments needs a review system outside of reader votes, and perhaps that is now happening.  It would be a good thing.  Some people are abusing the system.  Prior to today I have had a couple of other comments removed that CC agreed met civility standards and reposted after I complained.  This time I did not email them, but perhaps they're improving their system.  I hope so, because it is a good idea.  

I still think doing the best job possible of requiring people to post under their actual names is the most effective way of keeping the discussion civil.  There will always be those who don't care, but most of us want to be seen as decent people.
