First of all, what is happening to Vanessa?! She used to be such a nice girl, but now is reduced to stealing BlackBerrys and stalking chicks on Foursquare. In last night's episode of Gossip Girl, Vanessa is on a mission to find out the truth about Juliet, tracking her down by using her Foursquare check-ins, then pays off Juliet's apartment manager to let her into her apartment. Scandalous!
Location-based services aren't for everyone, especially those that are worried about home security and privacy, so I guess Vanessa is right — Juliet should "move to a safer neighborhood" where building supervisors don't take bribes for entry. Be honest — have you ever tried to track someone down using Foursquare or another location-based app?
