As I said before if the experiment was really only about the coffee and not about the money on the card then Jonathan should have his tweets update with units of coffee, not quantity of money.
The experiment was set up in a way where money was front and center and coffee was only secondary.Also, if it was just about coffee why have an API?
With this twist Jonathan's experiment is even more brilliant.
1) Sam commented in the previous thread about buying food for homeless people from the card [2]
2) Sam's brother Daniel was one of the first to mention the possibility of the card being hacked [3]. His startup also funneled close to $600 into the card [4].
The whole thing started as a social experiment. Sam clearly considers what he's doing a part of the social experiment. I think it's still ongoing -- I fully expect another post, possibly later today or tomorrow morning, detailing the different reactions to his "I bought $25 of food for the homeless" comment and his "I bought $675 worth of food for starving kids in Africa" comment. Couple that with "me and my brother actually paid in what we took out" and we've got the makings of quite the experiment!

There is a difference between Random Acts of Kindness (Jonathan's card) vs charity.
I think making someones day a brighter place can have a tremendous knock-on effect. If an anon gave me a cup of coffee, I might be more willing to donate to charity for anons benefit. To "pay it forward"( http://en.wikipedia.org/wiki/Pay_it_forward)
I don't find it convincing the suggestion that it would have been more effective to donate that coffee as charity, as opposed to promoting a society more amiable to giving.
