The top 10 neighbors for Natasha Bertrand form a tight, undifferentiated cluster — scores run from 0.99 at the top to 0.99 at the bottom, with no single neighbor pulling away from the rest. That compression is the defining structural fact here.
Tallying the subcategories across the top 10: six are Journalists (Philip Rucker at 0.99, Katy Tur at 0.99, Kurt Eichenwald at 0.99, John Harwood at 0.99, Robert Costa at 0.99, David Frum at 0.99), one is a Politician (Sally Yates at 0.99), one is a Government Official (James Comey at 0.99), one is an Author (Molly Jong-Fast at 0.99), and one is a Professional (Preet Bharara at 0.99). The majority are fellow Journalists, but the non-journalist neighbors — a former attorney general, a former FBI director, a former prosecutor, and a political author — form a coherent secondary cluster: figures associated with law, national security, and political accountability rather than journalism per se. The audience shape here is not purely "journalism audience"; it is the overlap of journalism and the legal-political accountability space.
The flat shape means no single neighbor is a structural anchor. What the data reveals instead is a densely packed neighborhood where journalism and government/legal figures are nearly interchangeable in audience composition.
