If I'm looking for the latter I'm likely to ignore wikis. Consider Oracle's Java Tutorial vs. the Javadocs for the standard library -- if I'm looking for material more like the former, I'm likely to ignore a wiki as it's likely to be more like the latter, less useful until you're already up and running and need to look something up that you already know about. > And for a Quickstart guide to get Titan up and running in 5 mins, check > out Marko's blog: > > "Titan Server: From a Single Server to a Highly Available Cluster" > > http://thinkaurelius.com/2013/03/30/titan-server-from-a-single-server-to-a-highly-available-cluster/ > > Titan is the first native TinkerPop-Blueprints DB so you connect to it and > interact with it like any other Blueprints graph database ( > https://github.com/tinkerpop/blueprints/wiki). > > Think of Gremlin as a domain-specific language for graphs you use in > harmony with your native programming language.
