Walter Isaacson's highly anticipated new biography on Steve Jobs hit book shelves this week and reveals layers of a man most of us never knew. The book has kept Jobs in the global conversation and Howard Rheingold, visiting lecturer in Stanford University's Department of Communications and author of the book, "Smart Mobs: The Next Social Revolution," shares with us what he believes is missing from the conversation about Steve Jobs that all of us should know.

In nearly 50 years in the U.S. Senate, Kennedy compiled an impressive list of legislative achievements: on health care, civil rights, education and immigration.  From outside the Kennedy's house on Cape Cod, we're joined again by Sean Corcoran, senior reporter for WCAI. The Kennedy family legacy is far from exclusively American, however – it extends across the Atlantic to Ireland. We're joined by Irish politician and former Kennedy intern Mark Durkan, leader of the Social Democratic and Labour Party in Ireland, and one of the leaders of the power-sharing governments in Northern Ireland.

Since the day he took office, President Bush’s colorful speech has created a stir. Even in his ultimate exit interview, with a flourish of self-deprecation, he said, “Sometimes you misunderestimated me.” Over the years his turns of phrases have been not so much controversial as they’ve been cryptic. Hard to categorize, they sometimes sound like a joke without a punch line or a Zen Koan, imparting indecipherable wisdom. But the best way to describe them comes from Jacob Weisberg, who has coined them Bushisms and for nearly a decade he has been collecting them. Jacob Weisberg joins us for a retrospective of these presidential gems. And like all retrospectives we hope to gain a new appreciation for the man responsible for this body of work. Jacob Weisberg is editor in chief of The Slate Group and author of George W. Bushisms : The Slate Book of The Accidental Wit and Wisdom of our 43rd President.

In one of his final press conferences yesterday, President Bush patted reporters on the back with one hand while his other hand pounded the podium in defense of his presidential decisions. The mercurial nature of the conference left us wondering, is there any connection between how a president leaves office and their post-presidential legacy? To answer that question we turn to David Eisenhower the director of the Institute of Public Service at the Annenberg School for Communication at the University of Pennsylvania and grandson of President Eisenhower.
