Valentine's Day approaches. These days, it's not enough to line up a restaurant reservation. You have to post proof of the date online, and if your darling does, you'd better "like" it. Today, as part of "Love in the Digital Age," our occasional series on the way technology affects human relationships, Rachael Myrow chats with Rico Gagliano, co-host of the radio show and podcast "Dinner Party Download," about privacy. Look for Rachael and Rico's full conversation in the latest episode of "Love in the Digital Age" on iTunes, or wherever you download your podcasts.
