If you are employed as a journalist and have a free wheeling, anything goes Twitter/Facebook presence - be warned. The media companies are cracking down. We've already seen ESPN put a stop to it (you would think other Disney properties are next) and now the Washington Post has new social networking guidelines for employees.
I bring you this friendly warning to make sure you keep your job. In these times, you don't need to do anything that can jeopardize that.
