Followers by day
Tracking since Oct 31, 2026. 2 days of readings. Substack doesn't publish past follower counts, so history starts the day I first read a writer and grows by one reading every 3 days (daily if it's on your watchlist). The 7-day change appears on Nov 7, the 30-day change on Nov 30. Recommendation dates below go further back: they're Substack's own.
