The 5-Minute Interview: Karl Urich, DataFoxtrot` Karl Urich's first Neo4j project was four or five months ago, where he used Wikipedia data to solve a problem involving both spatial and graph data. He chose Neo4j because it is free, easy to use, and has good support and integration with other technologies. Karl found the power of using a purpose-built tool for analyzing graph and relationship-based data to be particularly useful, allowing him to achieve success and experiment with the technology. If he could start over, he might consider formal training, but notes that Neo4j was so easy to use that he didn't see any need to do anything differently. After attending a conference talk on graphs, Karl expressed his enthusiasm for Neo4j and encouraged others to share their own experiences in future interviews.
