Trust Me, I'm Lying by professional media manipulator Ryan Holiday.
Yeah yeah, we all know you can't trust everything you read on the internet--this guy proves you can't trust
anything, with detailed examples of campaigns he personally ran, online firestorms you will recognize that he manufactured out of nothing, and how bullshit makes the leap from bloggers to "respected" news outlets, while still retaining 100% of its bullshit. Fascinating in a horrifying kind of way. You think you're cynical, but not nearly as much as you will be after this book.
Dana, be warned: the author clearly recorded the audiobook version just sitting in his office, and the room reverb is bad. It's only tolerable if you keep the volume relatively low.
