I will give you a subject this brand has already published on several times.

First, list the angles it has been covered from, with the matching piece. Group by approach:
explainer, opinion, case study, common mistake, comparison, behind the scenes, data.

Then tell me which of those angles have not been used for this subject, and for each one write in
a line what the piece would say.

If every angle is exhausted, say so. Do not invent a new angle just to fill the list: a subject can
simply be done.
