Colin Quinn's ten nearest neighbors split almost evenly between comedians and actors — a mix that holds across a narrow similarity band, from Seth Meyers at 0.93 down to Kevin Nealon at 0.92.
Similarity here measures how closely two entities' audiences resemble each other in composition. The flat shape means no single neighbor pulls away from the pack; the spread across the top 10 is just 0.016. Within that tight band, four neighbors are classified as Actors — Michael McKean (0.93), Albert Brooks (0.93), Julia Louis-Dreyfus (0.93), and Jason Alexander (0.92) — matching the four Comedians: John Cleese (0.93), Ricky Gervais (0.93), Mel Brooks (0.92), and Nealon. The remaining two slots go to a TV Personality (Seth Meyers) and a TV Show (Late Night with Seth Meyers, 0.92). The actor contingent is notable: McKean, Brooks, Louis-Dreyfus, and Alexander all carry strong comedy-adjacent careers, which likely explains why their audiences overlap with Quinn's despite the subcategory difference. The cluster has no athletes, no musicians, and no non-entertainment figures in the top 10.
The overall picture is an audience defined by a specific comedy-and-performance sensibility — one that doesn't distinguish sharply between stand-ups and comic actors.
