We're used to thinking of "obesity" in physical terms — unhealthful weight that clogs our arteries and strains our hearts. But there's also an obesity of information that clogs our eyes and our minds and our inboxes: unhealthful information deep-fried in our own preconceptions.
In The Information Diet, open-source-Internet activist Clay Johnson makes the case for more "conscious consumption" of news and information. Johnson, the founder of Blue State Digital, which provided the online strategy for the 2008 Obama campaign, talks with NPR's Scott Simon about ways to slim and stretch our minds.
