Gremlin is a practical query language designed for developers and has very little (maybe zero) usage in academia. SparQL is the more established option which does get some academic (and production) usage, particularly as a lot of research on graph databases has a cross over with semantic web research.

This isn't the first time I've seen you criticise the "academic elite". You seem to use it as a crutch, an excuse for sloppy thinking and poor quality software.
