On Episode 216, "Allegra Rosenberg," Elizabeth and Flourish talk to the fandom journalist and Terror Camp organizer about her journey from tween fan reporter to writing a book about the pre-digital history of fan culture. Topics discussed include coming of age on Tumblr, learning to put on IRL events while deep in music fandom, getting that fannish feeling from immersive theater, and, of course, Terror Camp, a fandom-academia hybrid event that celebrates fans' investment in historical research.
