Last read Nov 1, 2026 (UTC). Followers are not email subscribers. Substack lists only the newest 50 recommendations for each publication, so a recommender count of 50 or more is a floor. History starts Oct 31, 2026; Substack publishes nothing earlier.

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.

One reading a day, the last of the day. Marked: leaderboard steps (into the top 25, top 10, or #1). Followers are people who follow Seth Klein on Substack; they aren't email subscribers.

Substack lists the 50 newest recommenders of each publication. I add every recommendation found in the full lists of the 6,392 publications I read, so writers with many recommenders may still be missing a few small ones. "Started" is Substack's date.
