#14 of 44 on Reddit420 people · Claude 14,112 (#1)
44 ranked subjects, each a tick on Reddit’s own people scale, 0 to 14,112. 41 more subjects aren’t ranked: their people figures are hidden (n 0–19 people, below the threshold of 20), so they aren’t drawn.
Not ranked on Hacker News: n 0 people, below the threshold of 20 people.
Distinct people who posted about each subject on each platform, 23 Feb – 1 Mar 2026, as of 25 Sep 2026 19:30Z, from release 2026-W09’s summary table (published). Each strip is on its own scale and nothing is added across platforms: one person can post on several. arXiv, Google News and Exa carry articles, which have no authors, so they have no ranking by people.

Change compares this reading with the previous stored reading of the same subject, usually last week’s, and both endpoints stay visible with their dates. Each value carries its n; open it for its full conditions, coverage included. Stored weeks, above, cross eras, which marks a change in how weeks were captured: March era weeks were rebuilt from archives, with live capture from 7 Mar to 31 May, Archive backfill weeks were backfilled from archives (Reddit, Hacker News and arXiv only) and September era weeks were captured live from 16 Sep and filled in from archives.
