We use TriG for:

+ small, hand-written configuration files
+ small, system-generated configuration files
+ ontology exports
+ small and large data set exports
+ bundling applications for deployment between environments
+ custom RDF generation from 3rd party scripts & apps for import into Anzo
+ ...

Basically, it's Anzo's format of choice for any serialization of RDF. 
Given that:

a) All RDF within Anzo is within a named graph
b) We find TriG to be far more human-friendly than something like N-quads

...we tend to choose it as our default format for just about everything.
