Turtle aids demystification of RDF, SPARQL, and Linked Data. It serves 
the broadest user profile range which extends from basic end-users all 
the way up to programmers. In a nutshell, it also brings the file 
create, save, and publish pattern to Linked Data deployment. You don't 
need to own a domain, control an Web Server, or master content 
negotiation and re-write rules, in order to get going with the 
deployment of Linked Data.

It makes RDF more palatable to to JSON programmers.

Why bring this up at all (unless prompted by your audience) ?

Yes, abstract syntax and concepts guide is a massive improvement. All 
participants be praised for their effort here, it's major progress!!

If you can demystify RDF in 20 minutes on the back of Turtle, JSON-LD, 
and a much improved abstract syntax and concepts guide, you will have 
totally over achieved :-)
