A lot of the people reacting in the comments here are your professional peers. For some, it offends their religious or cultural sensibilities. For some, it offends their taste. Some associate swearing with linguistic laziness. Others associate it with uncontrolled anger. A few might associate it with an abrasive boss. For some swearing just means enthusiasm, but what I'm saying is you're going to get all sorts of different reactions, and it's hard to say exactly what array of reactions you're going to get. That said, if for you the only options are swearing or watering down your enthusiasm, by all means swear.
