Posting rhythm is a calendar. Editorial cadence is a breath.
A rhythm asks you to show up. A cadence asks you to wait until there is something worth saying. The two look almost identical from outside, and that is the trap — most accounts can run the rhythm for a year and never once feel the cadence land.
The playbook treats cadence the way a magazine treats its issue dates. Not a deadline. A promise. If the issue is not ready, the issue is not ready; if it is, it ships, and it ships as one thing, not as a pile of things.
Once you stop measuring success in posts-per-week and start measuring it in issues-per-quarter, the work begins to compound. Each post becomes a chapter instead of a billboard.
