While keeping the world informed about what you're doing is a hot trend, it's not necessarily a smart thing to keep strangers informed about your whereabouts. Huffington Post wrote this weekend that police in New Hampshire busted a burglary ring that targeted people's homes using Facebook status updates:
According to WMUR, "[i]nvestigators said the suspects used social networking sites such as Facebook to identify victims who posted online that they would not be home at a certain time."
Facebook launched a location-sharing app called "Places" in August. The service was meant to be an easy way for the social network's users to share their locations with one another, but some are worried "Places" might share too much
"Be careful of what you post on these social networking sites," Captain Ron Dickerson cautioned, according to WMUR. "We know for a fact that some of these players, some of these criminals, were looking on these sites and identifying their targets through these social networking sites."
