Keith Olbermann's top 10 neighbors form a tight, undifferentiated cluster of political media figures — journalists, TV personalities, and political blogs — with scores spanning only 0.94 to 0.97, a narrow band that signals no single dominant pull.
The shape is flat. Similarity here measures how closely two entities' audiences resemble each other in composition; scores near 1.0 indicate near-identical audience profiles. The top neighbor, Rachel Maddow Blog, scores 0.97, followed immediately by Rachel Maddow at 0.96 — the only blog in the top 10 alongside the only journalist subcategory entry at that tier. Lawrence O'Donnell (0.96) and Bill Maher (0.96) are both TV Personalities, the same subcategory as Olbermann himself, making them the two same-kind neighbors in the set. Jim Acosta (0.95) and Michael Moore (0.94) round out the top six, representing Journalists and Directors respectively.
Tallying the full top 10: four are Journalists (Rachel Maddow, Jim Acosta, Kyle Griffin, Chris Hayes), two are TV Personalities (Lawrence O'Donnell, Bill Maher), one is a Blog (Rachel Maddow Blog), one is a Director (Michael Moore), one is a Professional (Chelsea Clinton), and one is a Website (Daily Kos). No politicians appear in the top 10, though they are present in the broader neighbor set visible in the graph.
The flat shape across this cluster indicates that Olbermann's audience is defined by a consistent political media profile rather than any single gravitational affinity.
