4 weeks ago: > "Apple adds new "Limit Ad Tracking" feature to iOS 6" http://news.ycombinator.com/item?id=4545602 http://news.ycombinator.com/item?id=4545602 3 weeks ago: > "Google implements Apple's Ad Identifier for mobile tracking choice" http://news.ycombinator.com/item?id=4581781 http://news.ycombinator.com/item?id=4581781 Both hacker news submissions have zero comments. Why is it that a month ago no one cared, but now everyone is grabbing his tin-foil hat? Also I am pretty sure at least some of the more extensive iOS 6 reviews have mentioned the new "limit Ad tracking" feature. And aren't we presumed to be developers who uses this stuff? I did know that Apple had a replacement for the UDID. PS: On Schneiers blog one commentator claims that he/she was notified of the Ad tracking by a prompt in the iOS update. Sadly I have no updateable iOS 5 device here to examine that. But I think this was only an info for the new privacy pane, wasn't it?

Well, it's got a different headline and a different (arguably more reputable) source. But mostly probably luck. My impression is that if a story doesn't get votes for the minority of people who cruise the "new" section in the brief period of time where it's on the first page or two, it's dead.

> Both hacker news submissions have zero comments. Why is it that a month ago no one cared, but now everyone is grabbing his tin-foil hat? A story not becoming popular on its first (or second) submission is not necessarily indicative of its importance. Relatively few people see new links, and the success of failure of these links in "going viral" is in the hands of relatively few. So no, it's not necessarily that no one would have cared about this a month ago and it's not an indication of hypocracy on behalf of this community; there are significant random factors that play into the exposure any particular topic or submission will receive.

Addendum: It is explained (from the developers point of view) in the WWDC 2012 session "Privacy Support in iOS and OS X". https://developer.apple.com/videos/wwdc/2012/?id=710 https://developer.apple.com/videos/wwdc/2012/?id=710 The old UDID is splitted into three new API: 1. Application ID, which scope is the app and lifetime is till uninstallation of this app. 2. Vendor ID: scope is developer and lifetime is till uninstallation of all developer's apps. 3. Advertising ID (identifierForAdvertising or IFA): scope is the device and a new ID is created by "Erase all contents/settings" and it is not restored across devices (practically lifetime is lifetime of the device). This means when you start to use a new iPad it will have its own Advertising ID and not use that of your old iPhone, because the ID is not tied to your Apple ID account, but tied to a device. It is noteworthy that after Apple banned the usage of the UDID some developers and ad networks started bypassing Apples privacy rules and made their own open source ID replacement: https://github.com/ylechelle/OpenUDID/blob/master/README.md https://github.com/ylechelle/OpenUDID/blob/master/README.md But I don't know if this will be permitted in the future or you have to use Apples provided ID system (I would assume the latter).
