Seven of Pete Thamel's top 10 neighbors are fellow Journalists — a same-kind concentration that makes the two-peak shape worth examining more closely.
Similarity here measures how closely two entities' audiences resemble each other in composition. Stewart Mandel leads at 0.95, followed immediately by Dan Wetzel at 0.94 — two scores that sit noticeably above the rest of the set. That gap is the first peak. Both are sports journalists, and the cluster around them — Pat Forde (0.92), Jon Rothstein (0.90), Jeff Goodman (0.89), Bruce Feldman (0.87), and Brett McMurphy (0.87) — reinforces a tight college-sports-journalism neighborhood.
The second peak is structural rather than a single dominant name: three News Publisher accounts — The Athletic CFB (0.90), The Athletic CBB (0.88), and Skratch (0.86, a Website) — pull the shape away from pure journalist-to-journalist overlap and toward the institutional outlets that cover the same beats. These two neighborhoods — individual sports journalists and the digital sports-media brands they work alongside — define the two-peak structure. The lone non-journalist, non-publisher entry in the top 10 is Skratch, a Websites subcategory entry, which sits at the boundary between the two clusters.
The overall picture is an audience tightly organized around college sports journalism and its adjacent media infrastructure, with almost no drift toward entertainment, general sports, or other categories within the top 10.
