Can Notion serve as a shared second brain for humans and agents? One builder's tradeoffs

The author previously ran a second brain as Markdown synced to GitHub — agent-friendly but miserable for human management. He's now moving the human-facing side to Notion, made viable by Opus being strong at Notion setup and design.

With CRM, podcast tracking, and client portals already in Notion, consolidating the brain there means one source of truth for the team, the agents, and himself. But dual versions aren't a long-term strategy, so he's asking the community what becomes painful as Notion grows.

A real workflow tradeoff (agent readability vs human maintainability), though mostly a request for advice.
