The 5-Minute Interview: Mark Joslin, CTO of Maslow` Mark Joslin, the CTO of Maslow, discusses their Neo4j project, a card-based social network. The company chose Neo4j for its graph database capabilities, particularly in handling relationships and pattern matching, which is essential for machine learning and recommending content to users. Joslin highlights that Neo4j's ability to make relationships first-class citizens has been a game-changer, making it easier to understand and implement complex queries. He also praises Neo4j's power as a pattern match, allowing for both filtering and criteria application. In retrospect, Joslin wishes he had started using Neo4j earlier and would have built the app again with more experience in Cypher queries. The conversation concludes with an invitation to learn more about Neo4j and graphs compared to RDBMS through an ebook and a NYC Meetup.
