Think back on what you talked about with friends and family at your last gathering. The latest game of your favorite team? "American Idol"? An addictive hobby? The new movie blockbuster? In a serious moment, maybe job prospects, Afghanistan, the economic mess? We live in an information-drenched environment, one in which sports and favorite programs are just a click away. And the ease with which we can do this allows us to focus on mostly comforting subjects that divert our attention from increasingly real, long-term problems.
