The top 10 neighbors in Eric Garland's similarity graph are academics, politicians, government officials, and commentators — not other journalists. Similarity here measures how closely two entities' audiences resemble each other in composition; a score near 1.0 indicates near-identical audience shape.
The shape is flat: scores run from 0.97 to 0.96 with no single dominant neighbor pulling away from the pack. Laurence Tribe leads at 0.97, followed closely by Rick Wilson (0.97), Seth Abramson (0.97), John O. Brennan (0.97), and Richard W. Painter (0.96). Four of the top 10 are subcategorized as Academics, two as Politicians, and one each as Government Officials, Professionals, Humor Memes and Satire (The Hoarse Whisperer, 0.96), and Authors (Molly Jong-Fast, 0.96). No other Journalist appears in the top 10 — the audience shape is defined almost entirely by cross-kind neighbors drawn from legal academia, political commentary, and national security circles.
The cluster points to an audience organized around a specific political-accountability beat rather than around journalism as a profession.
