While there are some obvious trolls here on the ADN comment section, the comments here are no where near as bad as some websites I've seen - and never have been.  The main improvement from Disqus is the spammers have been mostly banished.  Hooray for that.  There is one "flaw" in civil comments, and that when we are asked to rate other comments, we are asked to rate if the comment is "good" or not.  On the civil comments website there is a user guide that instructs us to vote "no" if we don't agree with the comment, but if we do that, it leads to threats of banishment, so I think that most people just vote yes on everything - including terrible comments.  Civil comments should get rid of the "is this a good comment" vote, and just have us vote on if it is civil or not - especially if they don't really want our honest judgement on whether the comment is "good" or not.
