Anita Stahl, a freelance tennis writer and photographer and a PhD candidate at the University of California, Santa Barbara, studying women's tennis, tells Thirty Love host Carl Bialik what she learned after spending eight hours analyzing the gender inequity in 321 Australian Open Instagram posts, why a player union is a good idea but Novak Djokovic might not be the best champion of the idea, and what the debate over renaming Margaret Court Arena is missing. Produced and edited by Jorge Estrada, with music by Lee Rosevere.
