Nestlé and JWT have launched the Social Break app for KitKat, whose tag is "Have a break, have a KitKat." With the app, users can enter account details for Facebook, Twitter and LinkedIn and decide how often they want the application to post updates. JWT surveyed 19- to 26-year-olds in the U.S., China and Singapore, more than half of of whom said it took too much time it to keep up with their social networking commitments.
