Ari Berman's top 10 neighbors form a tight cluster of journalists, news publishers, and political figures — with scores compressed into a narrow band from 0.99 down to 0.98, the defining feature of a flat shape.
Four of the ten neighbors share Berman's own subcategory of Journalists: Ana Marie Cox (0.98), Ezra Klein (0.98), Chris Hayes (0.98), and Judd Legum (0.98). Two are News Publishers: Talking Points Memo (0.99) and Politico (0.98). The remaining four span Politicians — Tom Perez (0.98) and Neera Tanden (0.98) — one Activism organization, Indivisible Guide (0.98), and one Professionals entry, Chelsea Clinton (0.98). No single neighbor pulls away from the pack; the gap between first and tenth is just 0.008.
The subcategory mix — journalists, news publishers, politicians, and activism — points to an audience defined by political media consumption rather than any single format or figure. The flat shape means no one entity anchors this audience; it is distributed evenly across a coherent ideological-media ecosystem.
