This is worth a watch too if you have the time and inclination, especially as it features an interview with Stewart Brand. I can't remember if he mentions The Well, but they certainly touch on the fact that Ted likely read the Whole Earth Catalogue, which started out as a back-to-land, survivalist publication but grew increasingly techo-utopian as it went on. The people he targeted were quite possibly users of The Well and, interestingly, there's also some cross-over between Ted's targets and Jeffrey Epstein's network, like the guy who founded The Edge.
