How X built the best fact-checking system on the internet | Keith Coleman (VP of Product) and Jay Baxter (ML Lead) | Lenny's Podcast: Product | Growth | Career | Podwise
This podcast interviews Keith Coleman and Jay Baxter, the product lead and founding ML engineer of Community Notes (formerly Birdwatch) on X (formerly Twitter). The discussion covers the platform's functionality, its surprisingly effective algorithm that leverages agreement from users with opposing viewpoints, and its impact on reducing the spread of misinformation. The team's lean operational structure, characterized by a small, highly focused team and agile decision-making, is highlighted as a key factor in its success. A concrete example is the 50-60% drop in post reshares after a Community Note is applied, demonstrating its effectiveness in curbing misinformation. Listeners gain insights into building high-impact products with small, empowered teams and the importance of transparency and user-driven development.
