Either take 63 seconds to view Mr. Clay’s ideas in video form, or read this summary:

Healthy information consumption habits are about more than productivity and efficiency. They’re about your personal health, and the health of society. Just as junk food can lead to obesity, junk information can lead to new forms of ignorance. The Information Diet provides a framework for consuming information in a healthy way, by showing you what to look for, what to avoid, and how to be selective. In the process, author Clay Johnson explains the role information has played throughout history, and why following his prescribed diet is essential in today’s information age.

That sounds very important and worthwhile.  The hardcover edition of the book is available on Amazon (for $13.79: the discounted value of advice?).  When you read the bio of the author on the Amazon website, sounds like it will be a worthwhile purchase at that price, based on who the author has worked with and for:

Clay Johnson is best known as the co-founder of Blue State Digital, the firm that built and managed Barack Obama’s online campaign for the presidency in 2008. After leaving Blue State, Johnson was the director of Sunlight Labs at the Sunlight Foundation, where he built an army of 2000 developers and designers to build open source tools to give people greater access to government data. He was awarded the Google/O’Reilly Open Source Organizer of the year in 2009, was one of Federal Computing Week’s Fed 100 in 2010. He claims to have learned most of what he needs to know working as a waiter on the late shift at Waffle House for two years.
