In the latest (fifteenth!) installment of “Ask Fansplaining Anything,” Flourish and Elizabeth tackle a new collection of listener letters. Topics discussed include defining “canon” in RPF fandoms, the sad fate of fandoms on Twitter, and what to do about non-fandom friends who judge your fannish activities. Plus: a query about the hypothetical legality of physically printed fanfiction in libraries, with an answer from *actual lawyer* and copyright expert Earlgreytea68.
