>While sometimes viewed as lazy or boorish, swearing actually requires substantial verbal facility and skill. When used correctly, in other words, profanity is expressively complicated

I'm glad they pointed this out -- as I always say, swearing is the inevitable linguistic crutch of the inarticulate motherfucker. However, this article missed out on one of the more important beneficial aspects of swearing, namely pain relief [1] (I could have linked a study or two, but they can be found in the wiki article for once, and this is more concise). Of course, as interested parties will learn, its analgesic effect is most prominent in those who rarely swear, so, not that personally useful.
