FireMe! mines Twitter (either your personal account or Twitter as a whole) for incriminating work-related tweets. So go to the site's homepage, and you'll see a public shaming of people tweeting things like: "My boss is an idiot," and "I hate my job." There's also subcategories you can look at. "Horrible Bosses," (standard hate) "Sexual Intercourse," (just use of the F-word, pretty much) and "Potential Killers" (people hopefully kidding about shooting their bosses) are included. If you enter your own personal Twitter account, it'll calculate your odds of getting fired if your boss sees your account.
