How is this for an interesting use of your data on Facebook? To announce their arrival on Facebook France’s Bouygues Telecom released an application that would create an actual book of your most important Facebook content. Users could select up to 10 friends and a certain time frame from which to pull all the content together. This was then printed off into a gloss hardback book in the Facebook colour and the users name in a Facebook style font on the front. This was limited to a run of just 1,000 book’s which were all snapped up within an hour.
