Nostalgic social network 'Timehop' loses data from 21 million users

A service named "Timehop" that claims it is "reinventing reminiscing" - in part by linking posts from other social networks - probably wishes it could go back in time and reinvent its own security, because it has just confessed to losing data describing 21 million members and can't guarantee that the perps didn't slurp private info from users' social media accounts."
