You're a PM for Facebook. Friend requests are down 10%. What would you do?

Focus on identifying potential causes for the decline in friend requests. Start by analyzing user behavior data to determine if the drop is consistent across demographics or specific to certain user segments. Consider conducting user surveys or interviews to gather qualitative insights. Propose actionable strategies to address the issue, such as enhancing the friend suggestion algorithm, improving onboarding for new users, or introducing features that encourage social interactions. Finally, outline how you would measure the effectiveness of your proposed solutions to ensure they lead to an increase in friend requests.
