Search covers subjects, readings, releases, communities, measured statements, quotes as pages show them, the glossary and the method. It never searches posts: the posts behind each figure are its fixed sample, on its page.

Weekly releases

Releases

Every weekly release, one ISO week at a time, and what each stored week found: who led on each platform, and how each week was collected.

  • captured: live, 7 Mar – 31 May, and from 16 Sep
  • backfilled: Reddit, Hacker News and arXiv loaded once from an archive after the fact, not collected live

The 53 ISO weeks of 2026, each in the month that holds its Thursday; releases as stored at 8 Oct 2026 12:00Z. Under the cells, capture by day: captured live 7 Mar – 31 May, and from 16 Sep; nothing captured live in between, where Reddit, Hacker News and arXiv were backfilled from archives, and a stored week’s other days were rebuilt from archives. A week can have a release only when it was captured or backfilled. Weeks join across the eras; a change of era marks a change in how the weeks were captured.

Blueskyits own ranking, by distinct people
Nobody ranked. Not counted this week: Bluesky has no day between 7 and 13 September 2026 that AIDRAN counts, so there’s no figure to show.

arXiv · Exa
Nobody ranked, in any week. The stored reason: “arXiv posts are articles, which have no authors, so people aren’t counted”; the same holds for Exa.

Each platform ranks on its own; values are never compared across platforms.

The #1 subject on each platform’s stored summary table, ranked by distinct people who posted about it in the release week, with n, the posts behind it. Windows: W37 7–13 Sep 2026, W38 14–20 Sep 2026, W39 21–27 Sep 2026, W40 28 Sep – 4 Oct 2026; as of 8 Oct 2026 12:00Z; published. Partial coverage: Bluesky in W37, YouTube in W37, Reddit in W38, Bluesky in W38, YouTube in W38 and Hacker News in W38, as each cell says. Values are never compared across platforms.
