Jim Adams, who managed spacecraft design during the Space Race, taught at Stanford, and has written some great books about engineering and creativity, likes The Distraction Addiction.

The book is both fun to read and thought provoking.  It reminds us that there are tremendous resources and very bright people tempting us toward seemingly being busily, if not frantically, involved with each other and the world, but maybe neither accomplishing as much as we might that will affect ourselves or others in the longer term, nor taking proper advantages of other ways to enjoy life…. He not only reminds us of the traps of existing with the internet, but suggests ways to better avoid them, including such things as digital sabbaticals and taking advantage of software such as Freedom. He clearly feels that we should be more mindful of the mind, as do I.

Just in the interest of full disclosure: I've met Adams a couple times, when I was postdoc at Stanford, but there's no reason he should remember me. The university is littered with smart young people who come and go.
