John Green is the strongest pull in Bo Burnham's top 10, scoring 0.89 — higher than any actor, TV show, or fellow comedian in the set. That an author sits at the top of a comedian's similarity graph is the first signal that this audience is shaped by something broader than stand-up.

The shape is broad, meaning overlap is distributed widely across many neighbors rather than concentrated in one. Across the top 10, actors dominate by count — Blake Anderson (0.85), Anders Holm (0.84), Adam DeVine (0.84), David Harbour (0.84), and Nick Offerman (0.82) all appear — but the mix also includes two TV shows (Parks and Recreation at 0.85, which connects directly to several of those actors), two podcasts (My Favorite Murder at 0.84 and Last Podcast on the Left at 0.82), and Hank Green (0.84), a second author. Only one fellow comedian appears in the top 10: Matt Bellassai at 0.80. The subcategory distribution — actors, authors, TV shows, podcasts, and a single comedian — points to an audience organized around a specific cultural register (literary-adjacent, ensemble comedy, narrative podcasting) rather than around the comedian category itself.

The breadth of this neighbor set, spanning five distinct subcategories with no single one overwhelming the others, suggests an audience whose shape is defined by taste clusters that cut across media formats.
