Considering I once worked at a company (in the US) where one programmer had for his Do Not Disturb sign a page that said "FUCK OFF" in giant letters, um... yeah? Granted this was in the video game industry. But actually even in my current corporate business application development job there's a healthy amount of swearing within the department, even from the boss. We don't use it when communicating with people outside the department though (well, usually).
