As you will read more about in this issue's cover story on book marketing, this is one of the latest additions to S&S' online marketing strategy. Tips, I'm learning, are a major component of the FourSquare experience. When you check-in at a particular location, you can browse tips on that location provided by friends, other users and businesses/brands—everything from a meal recommendation at a restaurant to a notification about an in-store promotion. S&S' tips provide FourSquare users with a variety of interesting tidbits drawn from its books and authors—tips that users can then share with their friends on Facebook and Twitter, and tips that encourage them to learn more from the related book titles. For example, if I check-in at New York City's Minton's Playhouse, an S&S tip will inform me that jazz legends like Thelonious Monk pioneered bebop there, and that I can learn more in Robin D.G. Kelley's book about Monk. Simply put, this is way cool.
