Bill Hamilton mentored Kenneth Folk, and Kenneth (2nd site with media) mentored a bunch of people including Daniel Ingram of Dharma Overground, as well as Owen and Nikolai who participated in the study and are on the podcast. Owen is still apparently doing the Hamilton Project website, and Nikolai has a site called Down the Rabbit Hole documenting his post path journey. That should be enough links.
