I'm not sure how this got into my Audible list - best guess, it was on sale, and I mistakenly thought it was Christian Rudder's book about the analytics of OKCupid data. But it's not. It is somewhat interesting, but really just boils down to a history and catalog of online dating, past to present, interspersed with some anecdotes. There's very little actual analysis or psychology. So if a reasonably comprehensive catalog of the history of computer dating interests you, then go for this; if not, go for something like Rudder's book which has actual analysis.
