Comparable to Foursquare and Gowalla, Facebook’s latest feature Places let’s you check into a location and alerts you if any of your Facebook friends as well as any other Facebook users have checked into the same place, upping the creep factor and creating the potential for more awkward social situations than ever. Say you check into a bar. No one you know is around, but Places tells you that Melissa, a 32-year-old Art History major who watches “True Blood” and is a fan of Obama and a member of the group “I love chips and salsa” is within a 10-foot radius. Now you have an in. Once you casually stalk her out you can pepper the conversation with your take on last week’s episode or that article you read in Newsweek about Freud, right before you ask her if she feels like splitting some chips and salsa.
