Beijing office worker Jiang Hui surfs the internet looking for love at a cafe in Beijing on February 5, 2010. By joing an online dating site, Jiang, who hasn't dated a girl since graduating from college four years ago, hopes this Valentine's Day - which falls on the same day as the first day of the Chinese new year this year- will be different as he began his cybersearch for a sweetheart three months ago, utilising an exploding industry as millions of young Chinese like him take advantage of technology and a newfound freedom to control their own love lives.

Dan Slater joins the show to decode some of those and talk about new book, "Love in the Time of Algorithms: What Technology does to Meeting and Mating."
