Instead of a centralized 'People You May Know' algorithm, Substack enables writers to explicitly recommend other newsletters. This leverages the trust readers have in a specific writer to drive high-intent subscriptions to others, creating a viral loop based on human curation rather than machine optimization.
Core Principles
- 1.Human Curation: Writers manually select who they endorse, ensuring quality signal.
- 2.Contextual Relevance: Recommendations appear immediately after a user subscribes, capitalizing on high-intent moments.
- 3.Reciprocal Growth: Driving subscriptions for others creates a goodwill loop where they reciprocate.

"What if we just asked writers, who do you recommend? What if we just put that in the subscribe flow and just made it as simple as possible?"
