However, your light is hidden under a basket, to use an old metaphor. I'm having to go digging to find the genuinely new things going on. I suggest recalibrating the entire documentation with a focus on the new stuff. People on HN often complain about not having syntax examples front and center but I would say for you, the very first thing I you should be hitting your new visitors with is the choreography idea.
Set up a simple example of doing something like a concurrent remote counter that is atomically safe by the construction of your language and immediately dive in to what that means. Forget even educating us on the rest of the mundane syntax of the language, immediately dive in to what that is and what that means. I see in the docs/ dir that it probably hurts your programmer mind to cover the choreography before covering sections 1-8, but you can safely assume that if you intrigue with the choreography that they'll hang around to learn about the rest, whereas you can't safely assume that a new reader will wade through all the rest of the relatively mundane details to get to the really interesting stuff.
A modern language with a modern take on compiling a "program" that takes a unified view of the world at the programming language level, and then emits a "server" and a "client" (and perhaps other roles) as separate executables is a pretty nifty idea. Hit it early and hit it hard.
