I hear very regular complaints about the behavior of people posting comments on the stories at KansasCity.com. In fact, I've seen three just this morning.
Here's a newsflash: Sadly, lots of people use the anonymity of the Internet to be rude, spiteful, vindictive and deceptive.
It's a headache for many Website operators. Some topics are especially likely to generate nastiness: Crime and race are always particularly hot ones, obviously. The rivalry between MU and KU generates some of the most childish behavior I've ever seen, spilling over into comments about stories that have nothing to do with sports whatsoever.
Editors at KansasCity.com don't moderate the comments, but there is a link to "Report as Violation" with every comment. You can't police the Internet, and it's too bad that people can't keep their personal profanity and indecency filters operational.
This again points up the problem with sites like Wikipedia that encourage people to post content without identifying themselves: The cloak of anonymity gives people a forum not to put their money where their mouth is. It's all mouth, no money.
