How would you build a Facebook product for blood donation?

Focus on identifying the key user needs and motivations for blood donation within the Facebook ecosystem. Consider how to leverage existing social features, such as groups, events, and user profiles, to create a community around blood donation. Think about the user journey from awareness to action, and propose features that encourage users to donate, share their experiences, and invite friends. Address potential partnerships with blood banks and health organizations, and consider how to ensure user safety and privacy while promoting engagement.
