I'm not sure this is the "best stuff," but I'm currently reading From Counterculture to Cyberculture, and moderately enjoying it. It's about Stewart Brand, but really more about the scenes he was involved in, it's not a biography. Covers the Whole Earth Catalog and the WELL, but also talks about the influence of systems theory and Bucky Fuller, and clarified, for me at least, the difference between the New Communalists and the New Left, which were somewhat conflated in my mind. It also puts Stewart Brand as a character, if not an essential one, at some key events. The mother of all demos and the founding of the Homebrew Computer Club are what I'm referring to here.
