Others, such as the H3 Podcast which has 1.4m subscribers, and the even more popular Joe Rogan Experience podcast are also sold on Dr Peterson. He’s being talked about everywhere from 4chan (an anonymous message board) to anime forums. Dr Peterson even offered the 4channers a discount on his related self-help tool, the ‘Self Authoring’ programme – writing on Twitter: “Don’t stay in the underworld. Author your future.” (The merits of the programme - which is intended to help people “sort themselves out” - was the subject of a huge thread on 4chan.)
