Considering the many open sexual references he makes (it is part of life) in his posts.. I get the feeling, while generally and mostly "family" orientated.. I don't think he's so prudish as not to make use of the whole colorful spectrum of the English language.. if/when it suits his purpose.
I, for one, certainly wouldn't and don't mind it. But I'm not in the habit of cussing. I personally think it can make a person sound a bit ignorant, but it also comes in handy in certain circumstances.
At any rate, it's probably not him. That Steve says he's in Oregon.
