The top 10 neighbors for the American Civil Liberties Union span activism organizations, non-profits, news publishers, journalists, and comedians — with scores compressed into a narrow band from 0.99 down to 0.98, the hallmark of a flat shape.
Planned Parenthood Action (0.99) and Women's March (0.99) sit at the top, both classified as Activism organizations. Planned Parenthood (0.99) follows as a fellow Non-Profit. These three form the closest cluster, but the drop to the next neighbor is negligible: Michelle Wolf (0.98), a Comedian, lands at nearly the same score as ProPublica (0.98), a Non-Profit, and BuzzFeed (0.98), a News Publisher. Jamelle Bouie (0.98) and Ken Klippenstein (0.98) are both Journalists; Vox (0.98) and Reveal (0.98) are News Publishers.
The subcategory mix across the top 10 — two Activism organizations, two Non-Profits, three News Publishers, two Journalists, and one Comedian — reflects an audience that does not concentrate around any single kind of entity. The ACLU's own subcategory (Non-Profit) accounts for only two of the ten neighbors; the rest are drawn from media and individual voices rather than peer organizations. That cross-kind spread, with scores barely separating one neighbor from the next, points to an audience whose shape is defined less by organizational type than by a consistent orientation across activism, investigative media, and political commentary.
The flat distribution signals an audience with broad, evenly distributed overlap across a recognizable progressive-media and civic-advocacy ecosystem.
