Net Promoter Score + Feature Flags for canary releases

Canary releases involve deploying new features to a subset of users for early feedback and functionality verification. This practice originated from miners using canaries as air quality indicators in mines. Interestingly, some companies like People.ai push new features to their most satisfied customers (those with high NPS scores) who appreciate being the first to see new functionalities. LaunchDarkly's feature flag management allows for quick reversion to stable experiences if needed. This approach helps improve software quality and release speed by leveraging customer feedback.
