I read this on another blog last night, and I thought that it was something that we should all keep in mind. People are so passionate sometimes they don't realize they may be doing this. So here it is:
On this site, we observe the Lurkers Rule: The environment here should be so accepting, so calm and so non-screechy that most timid lurker should feel it's safe to comment. I won't let angry, vicious, annoying or repetitive people hijack the comment areas.
You can express any opinion you like, as long as it's on topic and as long as you express yourself without vitriol and without attacking others.
To reiterate: Be nice. To further quote from Alan Sepinwall's Rules for Commenting: "This is an opinion blog, and a place where people can and should argue passionately for their point of view. But there's a difference between arguing with passion and arguing with hostility. If you can't find a way to express your viewpoint without insulting other commenters, or getting strident and self-righteous -- say, equating your opinion with fact, and deriding other people for not seeing the truth of your words -- then either tone down your words until they're more respectful to other people, or don't comment."
