The Washington Post's nearest audiences are dominated by fellow news publishers, but the top 10 also pull in a philanthropy magazine, a non-profit, a public affairs TV show, and a former head of state — a mix that signals something beyond pure news readership.

Six of the ten neighbors are News Publishers: HuffPost (0.98), The Hill (0.98), Politico (0.97), Reuters (0.97), BBC News (World) (0.97), and The New York Times (0.97). The scores compress into a narrow band — the gap between the highest and lowest of these six is just 0.005 — which is the defining feature of a flat shape: no single neighbor pulls away from the pack. The remaining four neighbors break from the news-publisher cluster in instructive ways. The Chronicle of Philanthropy (0.97) and Gates Foundation (0.97) point toward a civic and philanthropic orientation in the audience. PBS NewsHour (0.97) adds a public-media TV dimension. And Bill Clinton (0.97), the lone politician in the top 10, suggests the audience overlaps with followers of Democratic-era political figures — a cross-kind signal that no other news publisher in the set shares.

The flat, tightly compressed shape indicates an audience that is broadly defined by serious news consumption, with a secondary civic and political layer that extends just beyond the news-publisher category.
