The top 10 neighbors for Denis Leary compress into a narrow band — 0.90 down to 0.88 — with no single dominant pull and no clear structural gap between them. That tight clustering is the defining feature of a flat shape, and the more telling finding is what the mix actually contains.
Comedians make up the plurality: Jim Norton (0.90), Ricky Gervais (0.90), Artie Lange (0.89), and Lewis Black (0.89) all sit near the top. Jason Alexander (0.90) is the only other actor in the set — meaning Denis Leary's own subcategory has just one representative among the ten closest neighbors. The rest of the cluster is genuinely cross-kind: Howard Stern (0.89) and the Stern Show (0.88) as a TV personality and a TV show respectively, sports journalist Peter Gammons (0.90), hockey analyst Bob McKenzie (0.88), and Magic Hat Brewing (0.88) as the lone brand. The Stern orbit — Stern himself, the show, and comedians closely associated with that world — gives the cluster a recognizable texture even without a single dominant neighbor.
The flat shape with a comedian-and-Stern-adjacent mix suggests an audience that follows a specific cultural register rather than a single entity type.
