Because discussions gather several posts of different significance, and since a few discussions have grown quite long, it would be great to let the posts exists by themselves.
The first step would be to add a "share" button like those of stack-overflow answers for instance. I feel like a good few options would be an url or a post-specific doi to be copied, and a tweet?
Antoine Lizee: Actually I like the idea of one "share" and one "cite" button. And to be clear - I think the post should still be shown in the context of the discussion, as it is now when you create the link by hand with the anchor (https://thinklab..../209#2 for instance).
