A changing index can feel fresh while every item keeps a permanent address. The useful question is not whether the idea sounds persuasive. It is whether it helps someone understand the work, make a decision, or complete a task with less friction.
What is happening
Randomizing both content and identity makes sharing impossible. Randomizing only presentation order preserves meaning.
This tends to become visible at the boundary between the organization and the person encountering it for the first time. Internal familiarity hides effort that remains obvious to a customer, reader, applicant, or collaborator.
A practical response
Shuffle the index at request time, but keep slugs, titles, dates, formats, and landing pages stable.
The aim is a smaller, clearer system: one source for the record, one visible hierarchy, and one next action that behaves as expected. That approach improves the immediate page and makes later application or database work easier to add without rebuilding the public surface.
