- Voice. The author speaks in the first person singular ("Every piece is something I shipped, built or got wrong") and addresses the reader as "you". Plain, declarative, a little dry. Evidence first: "with the evidence attached".
- Titles are claims, not topics. Sentence case, often two clauses with a turn: "Your judgment is fine. Your threshold isn't." "Everything is repricing." No colon-and-subtitle, no clickbait questions.
- Decks explain the claim in one or two sentences, never tease it.
- Name things by their job. Case studies are "Name — what it is": "Rubric — a PM-shaped eval tool".
- Promises are small and specific. "One essay every Tuesday." "Free. You'll get one email to confirm first."
- Punctuation.
- A long arrow → ends every link that leads on.
- A middle dot · separates meta ("BET · 15 MIN").
- Em dashes take a space on each side.
- Quotes and apostrophes are curly.
- No emoji, no exclamation marks.
- American spelling ("judgment", "color", "prioritize"). Source titles and names keep their own spelling.
- Never:
- Give a count of essays or case studies.
- Show the author's email address as text. The contact action is always Let's Meet. The tagline is "Product newsletter for product leaders and hiring managers".
