Why this one won
LinkedIn's business (recruiting, sales nav, ads) depends on members who actually engage with the network. Passive profile viewers don't generate the data that makes the platform valuable. The weekly engaged member metric filters out ghosts and captures the members whose engagement powers the whole business.

Lessons learned
Big account counts lie. The member who posts, comments or messages is the one who generates data, and data is what powers the revenue.

North Star
Weekly active creators sharing videos
Loom's viral wedge is sharing. A video that's recorded but never shared is a private use case with zero network effect. The weekly active creator metric captures both sides - someone recorded something AND they passed it on - and is the single best predictor of team expansion.

Weekly collaborating teams (2+ users on a board)
Miro solo is a whiteboard tool; Miro multiplayer is a team brain. The weekly collaborating team metric forces the product to focus on the use case that justifies the price: real-time and async team work. Solo boards are fine but they don't retain.

Daily active users who share a story, post or reel
Instagram's flywheel is creators - consumers drift, creators stick. Filtering DAU to those who share something turns the metric into a health signal for the network, not just attention. It aligns Reels, Stories and the main feed around the same goal: get more people creating, every day.
