Episode description as stored
Keith Coleman (VP of product) and Jay Baxter (founding ML engineer), the minds behind Community Notes, reveal how a small, scrappy team inside Twitter/X built the most trusted crowdsourced information system on the internet—one that’s changing the way we understand truth online. What you’ll learn: 1. How Community Notes actually works —a deep dive into the groundbreaking algorithm that rewards “bridging agreement” instead of majority rule 2. The seemingly crazy yet brilliant way this idea survived multiple CEO changes —from Jack to Parag to Elon 3. How this project started with a dumpster fire GIF (literally) —the untold backstory of its early launch 4. The secret to running ultra-fast, high-impact product teams —no OKRs, no Jira; just one Google Doc 5.
