I read a 1986 compilation of ten years from the CoEvolution Quarterly. We called it CQ. It was started and run for most of the first ten years by Stewart Brand. The owner of CQ was the Point foundation. Point was started with the $1.5 million in proceeds from the Last Whole Earth Catalog (which wasn't the Last). I was president of Point Foundation for 2 of the first 4 years and CQ published many articles by me.
Reading a summary of the only hippie...
Reading a summary of the only hippie intellectual magazine was revelatory. There were plenty of good and original thinkers who were part of the magazine: Bucky Fuller, Peter Drucker, Ivan Illich, Gregory Bateson, Herman Kahn and Marshall McLuhan. 
Stewart had a policy of including as many eclectic thinkers as possible, unedited. The consequence was that he got the intellectual core of the hippie era represented by two perspectives, not unrelated.
One group, the largest, was best represented by Wendell Berry. That group were pure Luddite. The modern world is an abomination, a moral outage and a desecration of sacred nature. Many people in that group sought alternatives to horrid modernity; the escapes ranged from organic farming, back-to-the-land purism, Indian living-in-teepees lifestyle, compost toilets and bioregional local governance. Plenty of apocalyptic thinking was on display of the Paul Erlich and global winter persuasion.
The second group, reflecting Stewart Brand's lifelong focus, were concerned with ways to conceive whole systems, global worldviews and the application of Bucky Fuller engineering to everyday life.
Intellectually, we still haven't seen the fruit of Stewart's quest. He is currently promoting Will Wright the creator of SimCity, a wholistic worldview person and Stewart has a foundation to build a 10,000 year clock.
The Luddite part of the hippie intellectual enterprise has been smashed by the steamroller of commerce running over an ant hill of romantic wishful sorrow. (Rejecting heirarchy, the hippies were unwilling to put a queen in the ant hill to make it work.)
The Luddite view and the whole systems view were related because the Luddities saw the past as a world that was more cohesive, easier to understand and better integrated with nature. Sort of a sentimental but mistaken, whole systems perspective.
