What today's Substack newsletters reveal
The September 12 Substack 10 is a near-total turnover at the top. Jingles Labs at 1 and Vanessa's Stitch Club at 4 are the clearest named entrants with verifiable backstory: ML/open-source writing for the former and a September 1 crochet-club launch for the latter. Intentional Luxury Bish climbing 5 ranks to 5 is the largest gain among holdovers.
Collapse Life falling from 3 to 7 and 鈴音 falling 8 ranks to 10 are the big slides. The Style Edit at 2 and Shield of the Republic at 3 are the security/fashion pair that climbed into the upper tier. The board does not mirror Charlie Kirk or September 11 anniversary traffic the way Wikipedia and Google News do on this date. Jingles Labs at 1, The Style Edit at 2, Shield of the Republic at 3, Vanessa's Stitch Club at 4, Intentional Luxury Bish at 5, The Install Edit at 6, Collapse Life at 7, Worship Design Studio at 8, Sivan Ayla Richards at 9, and 鈴音 at 10 are the stored order. The Substack Trending API page documents the feed.
