The British Ministry of Defence is worried about oversharing military personnel and their oversharing families, so they've created a few videos that should really make everyone think twice about careless tweets and Facebook status updates. In the video above, after checking in on Foursquare (which should be a crime in itself), the young sailors are seen dancing with scary terrorists who were tipped off to their location in a nightclub by stalking their profiles. So now they're all up in our Twitter, Facebook, Foursquare and probably even Myspace. That means no more tweets like, "I just disabled all security measures at ______ nuclear plant! LOL!" Ok?
