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 Razib Khan on Substack; they aren't email subscribers.

When the recommendations started

Live recommendations by the month each began, using Substack's own start date. Removed ones aren't listed by Substack, so they don't appear. Substack shows only the 50 newest recommenders, so before Nov 2025 (outlined) I see only those from the 6,392 publications whose full lists I read.

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.
