As far as PCs original post, I personally didn't notice excessively bad language. But that doesn't mean it's not bad, worse or normal.
Regarding workplace use, I wish! I originally did that at internship 2 of 4 on MPs forum, but haven't been able to since at any workplace since due to either filters, or my current line of work. Driving and meeting with people face to face isn't conducive to msg board posting. 95% of my small amount of posts therefore comes from my phone.
While I'm not versed on much phone tech for forums, I would also be down for a mobile device friendly theme, application or whatever else.
