All ten of Alex Burns's nearest neighbors are journalists — the top 10 form a uniformly same-kind cluster with no crossover into any other subcategory. Similarity here measures how closely two entities' audiences resemble each other in composition; scores across the top 10 span a narrow band from 0.99 to 0.99, the hallmark of a flat shape.

Ryan Lizza leads at 0.99, followed closely by Jonathan Martin (0.99), Glenn Thrush (0.99), Andrew Kaczynski (0.99), and Josh Dawsey (0.99). The spread across all ten — from Lizza's 0.9926 down to The Upshot at 0.9856 — is less than a single percentage point. No single neighbor pulls away from the pack; the cluster is essentially level.

The one structural note worth flagging: nine of the ten neighbors are journalists (the same subcategory as Burns), while the tenth, The Upshot, is a News Publisher — a publication rather than an individual. No other subcategory appears in the top 10. The absence of politicians, academics, or non-news media outlets in these positions underscores how tightly this audience is organized around political journalism as a category.

The flat, journalist-saturated shape indicates an audience that moves as a coherent bloc across political press figures, with little differentiation between individual reporters or outlets at this level of proximity.
