Eight of Craig Groeschel's ten nearest neighbors by audience shape are fellow Spiritual Leaders, with the remaining two — Dave Ramsey (0.94, Professionals) and a C. S. Lewis quote account (0.94, Fact Quote and Lyric Accounts) — sitting at the same score range as the rest. The cluster is as same-kind as similarity data gets.
The shape is flat: scores run from John Piper at 0.97 down to David Platt at 0.94, a spread of just three points across ten neighbors. No single figure dominates; the audience overlaps broadly and evenly across the evangelical Spiritual Leader subcategory. Louie Giglio and Pastor Mark Driscoll both sit at 0.96, Matt Chandler and Desiring God at 0.95, and Andy Stanley and Beth Moore at 0.94 — a dense pack with no structural outlier. Dave Ramsey's presence at 0.94 is the one cross-kind signal in the top 10, suggesting the audience extends slightly into personal-finance adjacent territory, but it does not disrupt the dominant pattern.
What the shape reveals is an audience defined almost entirely by its own kind: people who follow one evangelical Spiritual Leader tend, with high consistency, to follow others.
