I curse, but it's not a common thing for me. I only do so when I feel it's appropriate, like when I want to make a point to stand out. And for the record, I think it's goddamn ridiculous if you have to smurfing swear all the goddamn smurfing time, troutheads. It just makes you sound pretty dumb, imo.
So in conclusion: Swearing to make a point is good. Swearing just for the hell of it is bad.
