Episode notes
Subscription As Permission
- Subscriptions are permission to 'tap the shoulder' of a reader and let creators take creative risks that algorithms suppress.
- Direct relationships let creators override distribution algorithms and pilot unconventional work.
Algorithms Need Better Objective Functions
- Algorithms aren't inherently bad; their objective function determines outcomes, so design them to serve readers' interests.
- Chris Best suggests a Substack algorithm could prioritize reader value rather than ad revenue.
Design Ads To Align With Creators
- If you add ads or sponsorships, design them from first principles so incentives remain aligned with creators and readers.
- Chris Best warns against importing legacy ad models that pit platform against creators.
