Given the new enhancements in Neo4j 2.0, Dave Fauth has begun rebuilding his DocGraph social graph for organizing doctor data. He's also using the Mortar platform for easily handling Pig and Hadoop with Python.
You might be asking yourself, 'why do I need a MongoDB-like experience for DynamoDB when there are already full-MongoDB cloud services? One developer has written DyngoDB, which will provide the MongoDB-style interface in front of Amazon's DynamoDB and their CloudSearch service.
