Twitter isn't the best place to complain about your job or your boss, especially now. That's because a German app is out that compiles all tweets involving inappropriate comments about work. The FireMe! app retweets everything it finds via the FireMe! Twitter account, so your boss doesn't have to follow you on Twitter to see your 140-character rants.
The good news is that the FireMe app is also supposed to be able to scan your Twitte account to find any offending tweets before the sees them if you're feeling nervous at this point.
