You can try and keep your Facebook page safe from prying would-be employers, but you can't protect yourself against your own stupidity. One Australian family learned that the late last week. A 17 year old girl was helping her grandmother count a large sum of cash and posted a picture of the riches on her Facebook profile under the appropriately-named title "Large sum of cash." Seven and a half hours later, two masked men broke into the girl's mother's house looking for the loot, sporting a knife and a wooden club.
But as we said, the cash pile was 75 miles away at the girl's grandmother's house, not her mother's. (Oops!) Heck, the girl didn't even live with her parent any more. That didn't deter the knife- and wooden club-wielding bandits. They (presumably) terrified the three people who were home at the time, then (definitely) ransacked the house and made off with personal effects and a much smaller amount of cash.
Maximum PC? Maybe not. But it's a good reminder to keep sensitive personal info off of those social networks, especially, when said sensitive personal info includes pictures of large sums of cash and some sort of real name or location info. And please, if you must post pictures of your large sums of cash, make sure not to tag it "large piles of cash." C'mon now.
