A day counts once it has settled: once the posts still expected for it are below the threshold, or, for posts loaded afterwards from an archive, once they’re loaded. Coverage day by day is in this reading’s conditions. How coverage is recorded.
This reading was made with methods that are still being validated. Every figure says which state it’s in.

Claude Cowork in each platform’s table
Where Claude Cowork sits among every ranked subject on each platform. The heavy mark is Claude Cowork; every thin mark is another subject.
#16 of 41 on Reddit225 people · Claude 10,876 (#1)
41 ranked subjects, each a tick on Reddit’s own people scale, 0 to 10,876. 44 more subjects aren’t ranked: their people figures are hidden (n 0–18 people, below the threshold of 20), so they aren’t drawn.
Not ranked on Bluesky: n 16 people, below the threshold of 20 people. Not ranked on YouTube: n 3 people, below the threshold of 20 people.
Distinct people who posted about each subject on each platform, 28 Sep – 4 Oct 2026, as of 8 Oct 2026 12:00Z, from release 2026-W40’s summary table (published). Each strip is on its own scale and nothing is added across platforms: one person can post on several. arXiv and Exa carry articles, which have no authors, so they have no ranking by people.

Posts published 28 Sep – 4 Oct 2026, as of 8 Oct 2026 12:00Z; in development. People count distinct platform identities and are never added across platforms. Share is Claude Cowork’s posts over all posts AIDRAN captured on that platform in the window. Reddit’s posts include its comments. A normal share is claude Cowork's share of each platform's posts in the 17 earlier stored weeks of the same era (2026-W23, 2026-W24, 2026-W25, 2026-W26, 2026-W27, 2026-W28, 2026-W29, 2026-W30, 2026-W31, 2026-W32, 2026-W33, 2026-W34, 2026-W35, 2026-W36, 2026-W37, 2026-W38, 2026-W39), per platform.

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.
