"We are not thirteen-year old kids in the locker room. (There are ladies present, for that matter.) We are professional adults who are here to discuss the Perl programming language."
For all I know there are kids, or people who aren't computer professionals here asking for help and advice. I'm convinced that the latter use this site.
Update: for the record, people not being computer professionals shouldn't be a prerequisite for using this site IMHO. People have to begin somewhere, I think here is a better place than most.
