Medium, a social news and blogging platform, uses Neo4j to power its social functions. Medium chose Neo4j because it allows for the representation of users, posts, and collections as graph nodes with relationships between them, simplifying queries. Developer Evangelist Michael Hunger found that working with Neo4j's graph database felt natural, allowing him to easily store and retrieve data in a flexible manner. Graph Thinking is addictive, making it easy to identify connections between pieces of information, even in complex data. The story of how people came to appreciate the power of graphs has been shared by various community members, including Rik Van Bruggen, who found Neo Technology's vision resonated with him. A free copy of O'Reilly's Graph Databases ebook is available for download to learn more about graph databases and their applications.
