At 0.95, Jon Acuff — an Author, not a fellow Spiritual Leader — sits at the top of Timothy Keller's neighbor set, edging out Russell Moore (0.94), who shares Keller's own subcategory. That near-tie defines the two-peak structure here: the audience bridges a cluster of Authors and a cluster of Spiritual Leaders in roughly equal measure.

Similarity scores here measure how closely two entities' audiences resemble each other in composition — not thematic overlap. Among the top 10, three neighbors are Authors (Jon Acuff at 0.95, Bob Goff at 0.93, Ed Stetzer at 0.89) and three are Spiritual Leaders (Russell Moore at 0.94, Andy Stanley at 0.90, Matt Chandler at 0.90). The remaining four are media properties: two Magazines — Relevant (0.91) and Christianity Today (0.89) — one Blog, The Gospel Coalition (0.88), and one TV Personality, Sam Ponder (0.89). The media cluster reinforces the faith-oriented character of both peaks without belonging to either. No other subcategory appears more than once in the top 10 outside of Authors, Spiritual Leaders, and Magazines.

The overall shape is an audience that sits at the intersection of faith-based readership and faith-based leadership — drawn equally to writers and preachers within that world.
