They seem to implement a variety of graph centric APIs. From a query standpoint, it's easier to use a graph database to do something like find all the people who share interests with someone (person <--> interest <--> person), or find all the grand children in a family tree. Now whether or not Titan implements these performantly, I have no idea.
