What this question tests

Zero to one product thinking: defining a trustworthy dating product inside an existing social graph with sensitive privacy needs.

Users: Facebook users seeking dating who want it kept separate from their main social circle.
Pain points: existing dating apps lack the trust signal of a real, verified social identity, but users fear friends seeing their dating activity.
Prioritize: build strict separation from the main Facebook profile and friend list as the first design principle.
Solution: an opt-in separate dating profile using Facebook data for verification only, with friends explicitly excluded from matching by default.
Go to market: launch in a limited market first to test trust and safety systems before wide rollout.
Success metric: opt-in rate among target age segments, and match to conversation conversion, with safety incident rate as a guardrail.

Leads with the separation-from-friends design principle, the single biggest trust barrier for dating built on top of Facebook (common knowledge concern).
Uses Facebook's real identity data as a trust and safety advantage over anonymous dating apps, a legitimate differentiator.
Sets a guardrail metric, safety incidents per active user, appropriate for a sensitive product category.

Ignoring the privacy concern of friends discovering dating activity, the single biggest adoption blocker.
No safety or verification consideration despite the sensitive product category.
Treating this like a generic dating app with no tie to Facebook's actual identity advantage.
