EDEN, Utah — One morning last month, a group of roughly 60 people, including doctors, CEOs and internet entrepreneurs, gathered under a big white dome to hear the mission statement of their host, a 45-year-old man named Jamie Wheal.

As he paced back and forth in front of an altar bearing shiny Buddha heads, Mr. Wheal talked about the perils of information overload in our content-rich era. "A literate person in the European Middle Ages," he said, "consumed the same amount of content in their entire lives as we do reading a single edition of the Sunday New York Times."
