Physically preserving the contents of the web: in the second and final installment of their conversation with Craig Mod, Paul and Rich talk to the writer, designer, and technologist about his new book and about the writing platform hi.co, the entire contents of which will be printed on a tiny nickel plate and archived in the Library of Congress. They also answer a listener question about Paul’s anxiety—or, in his words, “brain space shenanigans”—and whether the frequent subject of Paul’s writing has any bearing on Postlight’s business.
