Hate your job? Sure you do. There's no shame in it. We've all been there, and many of us, sadly, will stay there for some time. Always remember, though: There are plenty of perfectly appropriate places to voice your professional gripes. That's pretty much why offices even have bars near them, but new Twitter service FireMe! is an excellent reminder that "on Twitter" is not one of those places. The very existence of this service -- which automatically aggregates tweets from people who hate their jobs -- marks the beginning of the countdown to someone finding out they've been fired through a well-placed RT.
