Given the number of Julia-related posts on the front page in the recent past, I doubt there is a need for a post linking to the generic home page for the language. That said, it would definitely be interesting discuss something unique or specifically interesting.
The most effective way to kickstart such a discussion might be sharing a blog post discussing a handful of specific aspects (could even have many of them). Then the HN discussion is likely to pick up on some of those themes. I think the current submission has not managed to provide a nucleus around which comments can crystallize — it’s too open-ended for drive-by commenters.
