Eight of Robert Kirkman's ten nearest neighbors by audience shape are actors, with scores ranging from Steven Yeun at 0.93 down to Michael Cudlitz at 0.81 — a remarkably uniform cluster for a broad-shape profile. Similarity here measures how closely two entities' audiences resemble each other in composition; the fact that an author's nearest audiences look like those of television actors is the structural finding.

The actor cluster is dense and consistent. Jon Bernthal (0.88), Melissa McBride (0.86), Katey Sagal (0.84), Emily Kinney (0.84), Chandler Riggs (0.82), and Norman Reedus (0.81) fill out the middle and lower tier with scores that barely separate from one another — the hallmark of a broad shape with no single dominant pull. The two non-actor entries are AMC Networks (TV Channels, 0.85) and Influenster (Other, 0.81). No other authors appear anywhere in the top 10. The absence of same-kind neighbors, combined with the concentration of actors and a single TV channel, points to an audience defined far more by a specific television property than by the literary category Kirkman occupies.

The shape reveals an audience whose identity is organized around a cast and a network, not around authorship.
