Anonymity and anger

Seems like more anonymous letters snailed to me these past few months. Angry people, mostly about politics. I suspect the pressures of the economy are manifesting themselves in various ways. I often don't wonder about one's need to vent, but do wonder about the need to vent anonymously. How have we in American and the media encouraged this?
If you're a regular Free Press reader or Web site "visitor" you know we dispensed with our "anonymous forum" that became a hate-filled, anger-induced baroom brawl. We ended it in part because we did not feel it was consistent with our "brand" as they say. We did not want to be seen as the sponsor of such hate, racism, sexism and gender bashing. Not only were we sponsoring it, we, in my opinion, were sort of enabling the perpetrators.
We then revamped the forum. You must use your real name, and you must agree to be civil. There is still some name-calling and uncivil discourse, but it's a level we can be more comfortable with. We can also monitor and control the conversation, issue warnings to violators and give them "demerits" electronically so everyone can see their "civility score."
We have generated a good amount of traffic to the site and have several regular contributors, and we thank them for their contributions.
It's an activity we can feel good about sponsoring and enabling.
