Alex Wagner's top 10 neighbors form a tight, undifferentiated cluster — scores run from 0.98 down to 0.96 with no single dominant pull and no sharp drop-off. Similarity here measures how closely two entities' audiences resemble each other in composition; the narrow band across all ten positions is the defining structural fact.
Tallying the subcategories: six of the ten neighbors are Journalists — Yamiche Alcindor (0.98), Chris Hayes (0.97), Elie Mystal (0.96), Joan Walsh (0.96), Kristen Welker (0.96), and Ari Berman (0.96) — the same subcategory as Alex Wagner herself. Two neighbors are Politicians: Tom Perez (0.97) and John Kerry (0.96). The remaining two are Professionals: Maya Harris (0.97) and Chelsea Clinton (0.96). No News Publishers, Activists, or other subcategories appear in the top 10, though they do appear further out in the broader neighbor set.
The mix is predominantly same-kind — journalists drawing journalists — with a consistent secondary layer of politicians and professionals whose audiences have converged on a nearly identical shape. The tight scoring range confirms this is a densely packed neighborhood with no outliers pulling in a different direction.
