Book excerpt: Edited by Canada's premiere commentator on global affairs, this must-read for political junkies will show the quailty of M&S's new Signal imprint: for everyone who wants to be well informed about international relations and the nature of the diplomacy in the age of Wikileaks. Inspired by Allan Gotlieb's capacity to reshape diplomacy for the times, the contributors to this volume grapple with the challenges of a digital age where information is everywhere and confidentiality is almost nowhere. With an introductory essay by renowned political scholar, writer, and commentator, Janice Gross Stein, the work is divided into 4 sections: Diplomacy with the United States in the Era of Wikileaks; The Professional Diplomat on Facebook; Personal Diplomacy in the Age of Twitter; and Where is Headquarters? Contributors include professional diplomats, award-winning journalist Andrew Cohen, former Globe and Mail editor and author Ed Greenspon, and Allan Gotlieb's wife and partner in 'social diplomacy', Sondra Gotlieb.
