StanceGrounded's top 10 neighbors span news publishers, TV channels, political groups, and political personalities — no single neighbor dominates, and the spread across subcategories is wide enough that no one cluster owns the shape.

The similarity scores run from 0.90 down to 0.84 across the top 10, a narrow band that confirms the broad shape. MSNBC leads at 0.90, followed by NBC News at 0.88 and House Democrats at 0.88. CBS Breaking News (0.87) and Keith Olbermann (0.87) round out the top five. Tallying the subcategories across all 10 neighbors: four are News Publishers (NBC News, CBS Breaking News, CNN Politics, CNN Breaking News), two are TV Channels (MSNBC, ABC News Politics), two are Political Groups (House Democrats, Senate Democrats), one is a TV Personality (Keith Olbermann), and one is a Comedian (Wanda Sykes). StanceGrounded's own subcategory — Activists — appears in none of the top 10 neighbors.

The cross-kind pattern here is the defining feature: an Activist whose nearest audiences are shaped almost entirely by news media and partisan political institutions, with no fellow Activists in the top 10.
