Use your Amex card, get a make believe cow
Is this even a technology story? I don't know. Whenever Zynga and Farmville and make believe cows get involved, I get all dizzy and disoriented. So American Express offers reward points when you use their cards. You can exchange those points for shopping at Amazon, dining out, going to movies, lots of stuff. And now you can use them for virtual (as in NOT REAL) goods through Zynga, the company that makes Farmville. So spend a bunch, get pretend farm equipment. OR better yet: don't because are you crazy what's your problem get something real instead.
