Book Riot's nearest audiences span authors, activists, journalists, politicians, and podcasters — a cross-kind cluster with no single dominant neighbor pulling away from the rest.

The shape is flat: the top 10 scores run from Margaret Atwood at 0.96 down to Jon Favreau at 0.94, a spread of just two hundredths. Similarity here measures how closely two entities' audiences resemble each other in composition; the narrow band means no single neighbor defines the shape. Tallying the subcategories across the top 10 confirms the mix: two Authors (Margaret Atwood at 0.96, Sarah Kendzior at 0.95), one Activism organization (Indivisible Guide at 0.96), one Magazine (Publishers Weekly at 0.95), one Website (Upworthy at 0.95), one News Publisher (NPR Books at 0.95), one Politician (Dan Pfeiffer at 0.95), one Comedian (Jon Lovett at 0.95), one Activist (Charlotte Clymer at 0.94), and one Professional (Jon Favreau at 0.94). No subcategory repeats more than twice, and the only fellow Website in the top 10 is Upworthy. The book-adjacent neighbors — Atwood, Kendzior, Publishers Weekly, NPR Books — share space with political media figures and advocacy organizations, a cross-kind pattern that runs throughout.

The flat, mixed shape suggests an audience defined less by a single content type than by a consistent sensibility that cuts across literary, political, and civic media.
