I picked this up after TED listed it on their Facebook page. I've used "Table Topics", a card deck with similar "Life, the Universe, and Everything" conversation-starter questions. Those are pretty good, but Rothbart took things another step by crowdsourcing questions while on a tour for Found Magazine, to eighty-something cities around the US. He then had a volunteer come up on stage each night, to whom he asked some of the questions. Rothbart's essays about those experiences using the questions, and about other conversations with strangers, add to the quality of the book. The questions are almost all in pictures of the slips of paper they were originally written on, and some are a little hard to read inline -- the contrast is too low -- but are ok once you click and zoom in on them (this is with a 3rd gen Kindle, with keyboard). I read this in about an hour with breaks to ask my wife some of the questions. Worth the three bucks just for her answers.
