you may be right about the check-in model, and if that's the case, using a blippy card might be a better model to broadcast purchases. and it'd be an easier way to consume the data on the client (ie push notifications when your friends spend using a blippy card, it's practically no different than a check in at that point). i use manual mode, and i don't publish the boring transactions like my gas purchases. you can decide whether to unfollow people if they have boring purchases, but it's still interesting to see which applications my own friends are buying on the iphone, for example.
