The top 10 neighbors for Russell Moore are overwhelmingly composed of fellow Spiritual Leaders — six of the ten positions belong to that subcategory — with the remaining four slots filled by adjacent evangelical media: an author, a blog, a magazine, and a quote account. The scores span a narrow band from 0.92 to 0.96, which is the defining feature of a flat shape: no single neighbor pulls away from the pack.
Ed Stetzer leads at 0.96, followed closely by Matt Chandler at 0.95 and The Gospel Coalition at 0.94. Timothy Keller (0.94), John Piper (0.93), Beth Moore (0.93), and Andy Stanley (0.93) round out the Spiritual Leaders cluster. Christianity Today (0.93) and C. S. Lewis (0.92) — the latter a quote-and-lyric account — sit at the edge of the ten alongside Louie Giglio (0.92). The non-Spiritual-Leader entries don't represent a cross-kind departure; they are all embedded in the same evangelical Protestant media world as the center entity itself.
The flat shape and tight score range together indicate an audience with a well-defined, internally consistent profile — one that tracks a specific corner of American religious media with little diffusion into other audience neighborhoods.
