Got A Smartphone? Want Free Coffee?

Jonathan Stark is trying out a little social experiment. He’s posted his Starbucks card image online and you can use it, free of charge. But he’s also made it so people can pay it forward, and add value to the card so somebody else can get a coffee. The live balance twitter feed shows fluctuations of the balance, when the card goes empty (which is often), etc… . It’s actually amazing to see people adding value back to it and how fast it goes away. This guy added $100 to the card, and it was gone in about 60 seconds.
