Ninety percent of Facebook Groups members never post β and measuring time spent hides it.
Most product leaders optimize for session length anyway. But a member scrolling silently for 20 minutes looks identical to one who sparks a 40-comment thread.

Time spent can't tell them apart. Consumption doesn't build communities. Contribution does.

Most product leaders go straight there anyway. But gift buyers don't fail at the results. They fail at the search bar. They know the person, the occasion, the budget. They just can't turn "my mom loves gardening" into a keyword. Better filters don't fix a translation problem.

One metric breaks that pattern: it only goes up when you catch more scams and stop wrongly flagging legitimate users. Inflate one side and the other pulls the score back down.

YouTube Shorts view time is up. Uploads are down. The obvious read: creator burnout. The real read: Shorts is losing a bidding war against brand deals, live events, and TikTok bonuses for the same creator hours.

Better tools won't fix that. Higher opportunity cost will always beat lower friction.

Have an upcoming DoorDash PM interview?
I created this cheat sheet to help you get up to speed.
Start here: master the three-sided marketplace (Merchants, Dashers, Consumers) β because multi-sided empathy is the lens DoorDash PMs think in.

Then drill these three pillars:
π§ Product Sense β decompose problems, know your metrics
π― Prioritization β R.I.C.E. framework smart trade-offs
β‘ Values & Ops β bias for action, ownership, fire drills

"What's the North Star Metric for Facebook Events?" has no obvious answerβand that's the trap. Most product leaders want to optimize event supply, user demand, and ticket revenue simultaneously.

If you have a Google PM interview coming up, start here. This cheat sheet maps all four areas Google evaluates, from first-principles product thinking to the cultural filter most candidates don't even see coming. Study it before you walk in the room.

Nothing more rewarding than hearing from readers finding their way into PM. Grateful for this note from a Carnegie Mellon Tepper MBA candidate.
