The flap over the NSA gathering Verizon metadata is way overblown. Metadata shows tendencies and trends, which is nowhere near as much privacy detail as what your smartphone is gathering or your internet postings contain. In other words: "The sky hasn't fallen....yet" ! Your smartphone (combined with internet postings) contain much more detailed information than you realize. While much can be made of its analysis (see the article below), it's not being tracked "real time" as depicted in 2008's film "Eagle Eye".
