Design Instagram.

Focus on the core features and user experience of Instagram, emphasizing visual storytelling and social interaction. Consider the primary user personas—content creators, casual users, and businesses—and how their needs shape the platform's design. Discuss the user journey from onboarding to content creation, sharing, and engagement, while also addressing aspects like discoverability, community building, and privacy settings. Be prepared to justify your design choices with user research insights and consider potential challenges such as content moderation and algorithmic bias.
