Andrew Mayne (0.89) and Ken Caillat (0.88) form two distinct poles at the top of Brian Brushwood's similarity graph — an Author and a Musician sitting nearly level, with the rest of the top 10 trailing behind them. That two-peak structure is the defining feature here: no single neighbor dominates, but two clearly separate audience neighborhoods pull in roughly equal measure.
The shape is two-peak, and the neighbor set is strikingly cross-kind. Brushwood is categorized as a TV Personality, yet only one other TV Personality appears in the top 10 — Shira Lazar at 0.80. The remaining nine neighbors span Authors, Musicians and Bands, Tech Personalities, Journalists, Actors, and Activism organizations. Susan Bennett (0.87, Tech Personalities) sits just behind the two leaders, followed by Jacob Dean (0.84, Journalists) and James Kyson (0.84, Actors). Further down, Scott Page (0.83, Musicians and Bands) and Bibop Gresta (0.83, Tech Personalities) reinforce a recurring tech-and-music thread. The two Organizations in the top 10 — NOH8 Campaign (0.82) and Change.org (0.81), both Activism — add a civic dimension that has no parallel in Brushwood's own subcategory.
The overall picture is an audience that bridges a creative-technical cluster anchored by an Author and a Musician, with civic and journalistic neighbors rounding out a profile that looks almost nothing like the TV Personality category it nominally belongs to.
