This is a kick ass stunt to promote a new Facebook app based on the question: what did you do 1 year ago today?

The service is called Timehop,  and it will send you text message updates of your Facebook statuses from one year ago, each day.   Interesting idea….but I’m curious to see how this app will survive long-term after the novelty has faded.  But I give them mad props for their attention to detail on the DeLorean.
