Facebook, MySpace threaten your job, savings
While they present a wonderful opportunity to meet people with similar interests, sites like MySpace, Facebook, and even LinkedIn can also cause trouble.
In his book Art of Deception, Kevin Mitnick, arguably one of the most notable criminal hackers in history, talks about how he used the phone, not the Internet, to con his way into various companies. Using social engineering, Mitnick was able to insert himself into the target company, often conveying up-to-the-minute information about managers and supervisors being on vacation in order for a subordinate to give him vital corporate information.
Today, penetration testers, professional gray-hat hackers who attempt to break into sponsoring companies, use these same social tricks to see whether employees will divulge key information. Often they do so the old-fashioned gumshoe way of walking into a branch office and somehow finagling the company phone book or organization chart out of some hapless employee.

It doesn't help either that Facebook has pretty much said 'expect no privacy'.
