"This reminds me of the early days of the internet, when phone number lookup sites began appearing. Before then, everybody’s number was public information, published in your local telephone book. You had to at least know what city someone lived in to find their number. But then someone built a website that took all of this public information and aggregated it into a single database, and all of a sudden it was easy to find everyone’s phone number *and* location. There was no extra information leaked here, but it was somehow unnerving, and I’m guessing it destroyed the phone book industry. Who lists their number now? Similarly, Timeline doesn’t provide any more information than was already available on Facebook, but it just does it in such a way that it’s somehow creepy."
