Seven of Maggie Haberman's ten nearest neighbors are fellow journalists, and the remaining three — a comedian, a government official, and an academic — sit within a fraction of a point of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; the top 10 span just 0.006 points, from 0.9963 down to 0.9902, which is the defining feature of a flat shape: no single neighbor pulls away from the pack.
David Fahrenthold leads at 0.9963, followed closely by Glenn Thrush (0.9947), Julia Ioffe (0.9933), and Josh Dawsey (0.9920). Ashley Parker, Josh Marshall, and Olivia Nuzzi round out the journalist cluster. The three non-journalist neighbors — Andy Borowitz (Comedians, 0.9919), Ben Rhodes (Government Officials, 0.9914), and Paul Krugman (Academics, 0.9913) — are interspersed throughout the ranking rather than clustered at the bottom, suggesting their audiences are nearly as compositionally similar as those of the journalists themselves.
The overall picture is a tightly bounded cluster of political media consumers, with no meaningful gap between the nearest and tenth-nearest neighbor.
