Jon Meacham's top 10 nearest neighbors are dominated by journalists and political commentators — a tightly composed cluster with no standout outlier pulling away from the pack. Similarity scores run from 0.97 down to 0.96 across the top 10, a narrow band that signals a cohesive audience shape rather than any single gravitational pull.
Joe Scarborough leads at 0.97, followed closely by Walter Shaub (0.97, Government Officials) and Willie Geist (0.96, TV Personalities). From there, the cluster fills in with journalists: Matthew Miller (0.96), Richard Engel (0.96), John Heilemann (0.96), Kasie Hunt (0.96), and Jennifer Rubin (0.96). The two non-journalists in the top 10 are Bill Kristol (0.96, Politicians) and Michael Beschloss (0.96, Authors) — the only fellow Author in the set. Tallying the subcategories: six of the ten neighbors are Journalists, one is a TV Personality, one is a Government Official, one is a Politician, and one is an Author. Meacham's own subcategory (Authors) appears just once in the top 10, meaning his audience shape is defined almost entirely by the political journalism and commentary world rather than by other authors.
The flat shape here reflects an audience that is broadly shared across a specific media-and-politics ecosystem, with no single neighbor commanding disproportionate overlap.
