Six of Rob McElhenney's top 10 neighbors by audience similarity are actors — a same-kind cluster that dominates the set — but the remaining four span enough distinct subcategories to signal something broader than a pure acting audience.
The shape is broad: no single neighbor pulls far ahead of the rest, and scores run from 0.96 down to 0.88 across the top 10 with no sharp drop-off. Glenn Howerton leads at 0.96, followed by Nick Offerman at 0.92 and Anthony Jeselnik at 0.91 — the first comedian in the set. Ed Helms (0.91) and Anders Holm (0.89) continue the actor run, but positions seven through ten introduce the cross-kind texture: It's Always Sunny (0.89, TV Shows), Cards Against Humanity (0.89, Toys and Games), Katie Nolan (0.88, TV Personalities), and BeerAdvocate (0.88, Websites). That last quartet — a TV show, a party game brand, a sports personality, and a beer-rating site — points to an audience shaped by irreverent comedy culture and craft-beer enthusiasm as much as by any single performer's fanbase. Kaitlin Olson at 0.89 rounds out the actor bloc, making six actors total in the top 10.
The broad shape, with its mix of actors, comedians, a TV show, a game brand, and a niche website all scoring above 0.88, reflects an audience that aggregates around a specific cultural register rather than a single genre or medium.
