There's a community version of the language being developed here: https://github.com/arclanguage/anarki

It works with the latest Racket versions and includes a HN clone. You can see it running here: http://arclanguage.org/forum

It's true that pg isn't working on it though. I wonder if he's ever getting back to it.

I'm not sure if its super important that PG gets back to it. To be honest, I'd love if someone made a summary of what, in 2017, makes arc unique and worth looking into.
