Zocalo Public Square is a not-for-profit daily ideas exchange that blends live events and humanities journalism. The entire initiative is a project of the Center for Social Cohesion at Arizona State University and the New America Foundation, and its goal is to "explore connection, place, big ideas, and what it means to be a citizen, be it locally, regionally, nationally, or globally." Visitors should look at the Ideas area to read meditations on subjects like "Do I have Any Business Being a Doctor?" and "Why We Keep Coming Back to Gatsby." The Books area is a real pip, featuring omnibus reviews (The Six-Point Inspection) and "Squaring Off," in which authors answer five questions about the essence of their books. Visitors shouldn't miss the Viewings area, which includes beautiful photographic essays on the Salton Sea, polling places, and the places where Americans gather. [KMG]
