Signal's top 10 neighbors span technology brands, tech-focused media, activists, and actors — a mixed cluster with no single subcategory dominating and no standout gap between the highest and lowest scores (0.94 to 0.91).

The shape is flat: GitHub leads at 0.94, followed closely by Malala Yousafzai at 0.93, Notion at 0.93, WIRED Science at 0.93, and Slack at 0.92. No single neighbor pulls away from the pack. Tallying the subcategories across the top 10: Technology brands account for three entries (GitHub, Notion, Slack), Magazines for one (WIRED Science), TV Shows for one (Silicon Valley at 0.92), Activists for one (Malala Yousafzai), and Actors for two (Kal Penn at 0.92, Kumail Nanjiani at 0.91). A blog (Gizmodo at 0.92) and a website (DEV Community at 0.91) round out the set. Signal's own subcategory — Social Media — appears in none of the top 10 neighbors.

The cross-kind composition is the defining feature here: the audience overlaps most with developer tools, tech journalism, and a cluster of South Asian–adjacent public figures, rather than with other social or messaging platforms. That pattern — tech-literate, civically engaged, media-curious — holds consistently across all ten neighbors without any single one anchoring it.
