Civil is something that has been regarded as increasingly important in the last year or so [1]. I have often heard it claimed that uncivil behavior is responsible for driving away new editors, and creating an unproductive editing and working environment.

However, I think it would be good to get some data on this. We have some anecdotal evidence that is a bit contrary to these claims:

I do think civility is important, but not for those reasons. Clearly, being the 7th most popular website on earth and the number one destination for all kinds of information, Wikipedia is very visible. And just like Al Jazeera and CNN and the BBC and the New York Times and Google and Yahoo and other high visibility information sources, we are under scrutiny as a result. And just like other high visibility sources, we have to present a certain inoffensive public image. A public relations disaster is just around the corner if we allow uncontrolled incivility and profanity behind the scenes at Wikipedia.
