In my opinion this view is getting weaker. I'm encountering more and more otherwise excellent technical posts or blogs that I'm unwilling to share with others because the author drops an f-bomb just for emphasis.
Does it really even matter what word you use if we already know what you're talking about?
In my experience, the people using the f-word in business interactions are the same people trying to con me. Maybe this is because several of my early experiences correlated this behavior with people trying to get me to join Ponzi schemes (these 'businesses' often target college-age people in the US).
