The Substack cascade now spans five distinct platforms, each serving a different engagement function. Substack Notes provides social bonding and conversation seeding. Substack Comments enables formal expertise exchange. YouTube Shorts drives breadth discovery and visual demonstration. Twitter builds rapid public presence and follower growth. The Village Hub aggregates cross-project visibility. Together they form a funnel: YouTube and Twitter drive top-of-funnel awareness, Substack converts to deeper engagement, Hub cross-links sustain attention, and Notes nurture relationships.
