fuck swearing

Firstly, my apologies. I didn't mean for that to be such a provocative title but it got your attention, eh? Where do you stand on swearing in blogs? I don't mean any random swearing but when it is used to show passion or expression. Does it further add to the fact I'm a Generation Y, 18 year old blogger? Or does it steal credibility, portray me as unprofessional and ward off potential employers or more importantly readers?...
