Damian, Damian, Damian, are you trying to say, jeans, T-shirt (obligatory smokes in left sleeve), and sneakers are not the normal dress for perl geeks ? You've burst my bubble. When I wear my Perl Mongers shirt (I got it before there was a Perl Monks shirt available), to work, folks ask me "Is that a new band ?" "Where are they from ?" They are the same folks that somehow mysteriously loose their network connection or get a blue screen of death during their MP3 downloads.... Still wondering why that happens..... :-)
If you're not constantly being reminded by your boss that you don't conform to the departmental dress code, then you are simply doing something wrong. RTFM !!!
