What today's Substack trends reveal
The September 28 Substack ten is an NFL-morning board. Pelissero at 1, Kim at 7, and Lombardi at 9 are three football writers on the same snapshot as Rams-Broncos Sunday Night Football (final 30-26). AI Investment Brief jumping 5 ranks is the non-sports exception. Craft and luxury titles (Vanessa, Intentional Luxury Bish) still occupy the middle, so the board is not a pure sports dump.
