Short answer: Way more than you think. Our own Eli Pariser laid it all out in this eye-opening TED talk, and got a standing ovation for his trouble. His book on the topic, The Filter Bubble: What the Internet is Hiding from You, is out this week — help make it a hit on Indiebound or Barnes and Noble.
Here’s what author Bill McKibben has to say about it: “You spend half your life in Internet space, but trust me—you don’t understand how it works. Eli Pariser’s book is a masterpiece of both investigation and interpretation; he exposes the way we’re sent down particular information tunnels, and he explains how we might once again find ourselves in a broad public square of ideas. This couldn’t be a more interesting book; it casts an illuminating light on so many of our daily encounters.”
