The top 10 neighbors for Josh Marshall are overwhelmingly fellow journalists — eight of the ten, spanning a narrow similarity band from 0.99 down to 0.99 — with scores so tightly clustered that no single neighbor stands out as a dominant pull. Similarity here measures how closely two entities' audiences resemble each other in composition; the compression of scores across the top 10 is itself the finding.
The eight journalists include Ryan Lizza and Julia Ioffe at 0.99, Glenn Thrush at 0.99, and Maggie Haberman and Josh Dawsey at 0.99, followed closely by David Fahrenthold (0.99), Greg Sargent (0.99), and Olivia Nuzzi (0.99). The two departures from the journalist subcategory are Andy Borowitz, a comedian at 0.99, and Paul Krugman, an academic at 0.99 — both sitting within a single point of the top-ranked neighbors. The near-total dominance of the journalist subcategory, with only marginal incursions from adjacent commentary-oriented figures, describes an audience that tracks political media as a coherent beat rather than branching into entertainment or general punditry.
The flat shape here signals a deeply specialized audience with consistent overlap across a well-defined professional cluster.
