Honestly, I think people don't realize that nastiness makes their comment less effective. Most people don't take you seriously if you insult them, even if the insult is followed by a valid point. How about something like this.... Create a set of general rules to follow for making an effective/polite post. Things like "calling someone a name brings more attention to the insult than your point." When you have a dozen of these or so, put a random one next to the "reply" button. This way people are constantly reminded of how to create polite posts.
