In my living room: social rules

I have been working to establish acceptable behaviors or use policy for several social networks that I am involved with. I came across this post by Shel Israel on the blog Global Neighborhoods. He enforces very similar rules as if those posting comments were in his living room. He states that,

"If you came into my home and were rude to another guest, I would ask you to stop. If you continued to be rude, I would ask you to leave. From this point forward, this is what I will do. If I feel you are being abusive, hogging the conversation or otherwise discouraging the open exchange of legitimate points of view. I will ask you to be more polite. If you ignore the request, I will ban you from further Comments. I call the the Living Room rule and I will enforce it subjectively."

He also sets a hard rule on anonomous comments / postings. He does not allow them.
