Top communities, each week

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

NotebookLM’s share of Hacker News posts is hidden in all 40 weeks: n 0 to 1 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.

State
In development: the method behind this reading is still being validated. NotebookLM’s posts were linked to it by rule run 541. On Reddit, 1 posts whose only match to NotebookLM 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
NotebookLM'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.
