Attention
How many people posted about Claude Cowork on each platform, and Claude Cowork’s share of that platform’s posts. One row per platform, each on its own terms.
Not counted this week. Bluesky and Google News have no day in this window that counts, so they have no figures here.
Reddit. People hidden: n 0 people, below the threshold of 20 people. Share and posts hidden: n 0 posts, below the threshold of 20 posts.
Hacker News. People hidden: n 0 people, below the threshold of 20 people. Share and posts hidden: n 0 posts, below the threshold of 20 posts.
arXiv. People not applicable: arXiv posts are articles, which have no authors, so people aren’t counted. Share and posts hidden: n 0 posts, below the threshold of 20 posts.
In development. Spam, bot and incentive posts haven’t been removed: their labels agree with a stronger model at κ 0.43, below the threshold of 0.60. The agreement is model-to-model.
Posts published 29 Dec 2025 – 4 Jan 2026, as of 25 Sep 2026 19:30Z; 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. There’s no normal share to compare with yet: a baseline needs earlier weeks of this subject. Choose any number to see what it rests on and the posts behind it.

Change
No reading of the week before, between 22 and 28 December 2025, is stored under method version 005c-series-v3.1, so no change is shown.
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.
