There's a new "grab your images from facebook and use it in a tailored clip ad" thingie out there, called Mentos Fresh News.
With enough wacky news stories out there to generate some surprising stories based on your facebook photographs, it's actually rather funny at times. Created by AD's Viv Yapp, Szymon Ros, CW's Ak Parker, Daniel Schaefer and the Digital Producer Paul Malecki from BBH, London, they went the extra mile to make 45 minutes of customizable footage, opening up for millions of variations.
If you use 4square, and have that attached to facebook, the news stories about you will be slightly more stalkerish, and just as sarcastic. Have fun.
