NPR has a fascinating story about the web, surveillance and one's expectations of privacy in an interconnected, internet-addicted world. Julia Angwin, an investigative reporter, was wondering what Google knew about her, so she asked the company for her search data. "It turns out I had been doing about 26,000 Google searches a month ... and I was amazed at how revealing they were." This has became the basis of her brand new book, Dragnet Nation. "From NSA sweeps to commercial services scraping our Web browsing habits, to all kinds of people tracking us through our smartphones, Angwin says we've become a society where indiscriminate data-gathering has become the norm." You can listen to her conversation with Fresh Air's Dave Davies or check out the accompanying story with some of Angwin's thoughts on surveillance.
