I don't really follow PP, but i get the impression that most of the content he posts is actually embedded video.. (andarchy probably has the same problem).
TBH, ive always kind of felt that writers that do that should transcribe and post text in addition (there are ppl of fiverr that would do it fairly cheaply)... after all, the whole point of putting content on a chain is so that its not under the control of a central actor
