Facebook or Twitter - Being too open with public sharing can invite crime
In my formal IT security training during 1990s, privacy concerns were expressed like "loose lips sink ships" or "don't say anything you would not want published on front page of newspaper'. These same principles apply to web 2.0 social networks as well. While one might feel safe in sharing with friends, however anyone on the Internet (including criminals) can read publicly posted comments.
Your Facebook profile: An open invite to crime?

QUOTE: If you don't care about your online privacy, why should Facebook or Google? Thirty-eight percent of the Facebook and Twitter users surveyed posted their holiday plans online, and 33 percent shared information about weekends away. "Coupled with the finding that an alarmingly high proportion of users are prepared to be 'friends' online with people they don't really know, this presents a serious risk to the security of people's home and contents," the insurance company said in a statement.
“Posting ‘My big-screen TV is awesome, wish someone was gonna be home enjoying it, but everyone's gone for three days’ isn't the brightest move in the world,” says this one police officer I know from Facebook. “But it's not as high on the list as say, leaving your front door unlocked or your garage door wide open.”
