 I'm Eric Deggans, and I'm TV critic and media analyst for NPR. I want to talk about Burn Book, a tech love story by Kara Swisher, this wonderful nonfiction book. Kara Swisher pulls off a magic trick here. She basically gives several books in one. One is her story of becoming media's most influential tech analyst, where she chronicles the rise of Facebook, Amazon, Google, ex-Twitter.
