13 out of 15! Zuckerberg's cell phone number! Maybe I'm being old-fashioned here, but this seems unequivocally wrong. Any app, from Angry Birds to Fart App 3000, can just grab the information in your address book without asking? Hell. No. And Curtis is right in calling Apple out about this...apps should not have access to address book information without explicitly asking. But now that the horse is out of the barn, this "quiet understanding" needs to be met with some noisy investigation. What happened to Path needs to happen to all the other apps that are storing our data. There's an opportunity here for some enterprising data journalist to follow Thampi's lead: investigate what other apps are grabbing address book data and then ask the responsible developers the same questions that were put to Path. Well put.
