An inside look at X’s Community Notes | Keith Coleman & Jay Baxter

Keith Coleman, product lead for Community Notes at X, and Jay Baxter, founding ML engineer for Community Notes, describe how the feature's bridging-based algorithm surfaces notes that people who normally disagree both find helpful, rather than relying on professional fact-checkers or majority voting. They trace the product's origin to an internal engineering contest, explain why every account, including Elon Musk's, is eligible for notes, and discuss how the small team survived four changes of Twitter/X leadership before Meta adopted the same approach.
