| Titan is used in production, and it's one piece of the Aurelius Graph Cluster (http://thinkaurelius.com/subscription/), which is some of the most impressive tech to hit the open-source scene in the last few years. Matthias Broecheler (https://twitter.com/MBroecheler) is the original creator of Titan, and he is incredibly bright. When he finished his PhD, he linked up with Marko Rodriquez (https://twitter.com/twarko), the creator of Gremlin (https://github.com/tinkerpop/gremlin/wiki), and they formed Aurelius to focus on building the big-data graph ecosystem (like Cloudera for graphs -- in fact, the Aurelius Cluster integrates with Hadoop and Cloudera). There are other distributed graph databases, but most of these are batch processing engines like Pregel. However, Titan is a real-time, transactional graph database backed by either Cassandra or HBase, and it provides fast, horizontally scalable write performance (10,000+ tps) that hasn't been available in an open-source graph database. See http://thinkaurelius.com/2012/08/06/titan-provides-real-time... Combining this with Faunus for batch processing and the Aurelius Graph Cluster's integration with the Hadoop ecosystem makes for an incredibly powerful platform for building applications such as social startups.
