Social Graphs vs Interest Graphs
Social graphs map the relationships and connections between individuals, typically representing friends, family, or acquaintances within a network. They focus on who you know. In contrast, interest graphs connect people based on shared interests, preferences, or activities, regardless of whether they have a personal relationship. While social graphs emphasize personal connections, interest graphs highlight common passions or topics, enabling discovery and interaction beyond existing social circles.

💡 Key Takeaways
- Differentiate social graphs (relationships between people) from interest graphs (connections by shared interests) and what each emphasizes (who you know vs what you care about).
- Identify the data signals each graph uses: social graphs rely on ties and interactions, while interest graphs rely on preferences, activities, and topics (often regardless of direct acquaintance).
- Understand how these graphs guide behavior on platforms, from friend suggestions and social discovery to interest-based content and communities.
- Consider privacy, bias, and cultural influences in how social and interest graphs are built and used in tech and internet culture.
