Neo4j is being actively used by its community members for a variety of applications, including Twitter troll analysis, graphy problem detection, and knowledge graph-based solutions such as NASA's talent mapping database. The community is also exploring the use of Neo4j with other tools like AWS Kinesis and Spark, and has developed open-source Python packages to facilitate data backup and transfer. Additionally, Neo4j is being used in creative ways, such as calculating the "Kanye Number" for artists using Musicbrainz data, and a fun demo showcasing its power with Cypher queries.
