Is online dating the death of monogamy?

>> your match and for others, it's a $2 billion industry. 1/3 of the single americans look for love online. there used to be a stigma, but that is gone. our next guest wanted to find out how the algo rhythms of love are create and to meet the consumer who is make it a big business . love in the time of algo rhythms rhythms. it sounds like a title if he was still doing that sort of thing.

>> the caller still existed.

>> i did steal the title a little bit.

>> there is more than just the fact that there was the link between the title and the book.

>> that's my argument and i'm sticking to it.

>> one of the most interesting things in this book is when you talk about the niching of these things, we all know about e harmony and match.com, but there is for military widows and the gaggle that encourages women to have relationships with multiple men. why do i find that fascinating? talk about the niching of the relationships by the social sites.
