What today's Substack publications reveal
The core board is still publishers, not headlines. Fashion, lifestyle, and craft fill 1, 2, 5, 6, and 10 (Sivan Ayla Richards, Callie Coles, Elsabratt, The Style Edit, Vanessa's Stitch Club). Shield of the Republic at 7 is the security exception after giving back two of the five ranks it gained on September 6.
The Neter's slide is a three-day staircase, not a one-day crash: 1 on September 5, 2 on September 6, 3 today. Callie Coles lasted a single day at 1. Conway's Case Notes holding 4 is the legal fixture that arrived yesterday and did not bounce.
Two names left to make room for Sivan Ayla Richards and Tretas Club. Aimee Song's 3 slot is gone. The Japanese audio-and-column title is gone from 9. Tretas Club is the Portuguese-language replacement at 9.
Labor Day did not insert a politics newsletter at 1. The new leader is a lifestyle writer, and the craft title at 10 did not move. get_growth was skipped; Substack rows are publications, not keyword sources.
