Hacker News is one community, so its row is the whole platform.

Microsoft Copilot’s share of Hacker News posts is hidden in all 40 weeks: n 0 to 5 posts, below the threshold of 20. As of 8 Oct 2026 12:00Z, the newest of four as-of times. Coverage: every day active in 1 of 40 weeks; the others have backfilled, partial or late heavy days. 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); September era weeks were captured live from 16 Sep and filled in from archives.

Conditions of this view

What every figure above rests on, stated once. Each figure’s own conditions are on its reading page.

Subject: Microsoft Copilot · product · Microsoft AI (subject id microsoft-copilot). Posts are linked to it by rule run 17 and checked by run 18.
Weeks: 40 weeks, W01–W40. Each is a release window, as its release stores it.
Counts as of: 25 Sep 2026 19:30Z, for 22 of 40 weeks (W01–W22); W23, W24, W25, W26, W27, W28, W29, W30, W31, W32, W33, W34, W35, W36 and W37: 25 Sep 2026 13:30Z; W38 and W39: 2 Oct 2026 04:00Z; W40: 8 Oct 2026 12:00Z.
State: In development: the method behind this reading is still being validated. Microsoft Copilot’s posts were linked to it by rule run 541. On Reddit, 386 posts whose only match to Microsoft Copilot is an ambiguous name aren’t counted. Frames and register aren’t measured yet.
Capture: Lines join across eras. 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); September era weeks were captured live from 16 Sep and filled in from archives.
Hidden: A share under 20 posts and a people figure under 20 people are hidden, with the reason each stores.
Baseline: Microsoft Copilot's share of each platform's posts in the 1 earlier stored week of the same era (2026-W01), per platform. Its figures are in those readings.
Method: 005c-series-v3.1 · aidran.assemble_release · every figure opens its own conditions on its reading page.
