OK, I have reread that post and it says this
If your site does not have an XML feed, Discourse will create topics based on your page contents using a readability algorithm. It’s remarkably accurate for those cases when your site doesn’t have a feed.
I cannot see how this works from the post end of things. How do you tell a post what page it should be using?
The other issue I have is that the URLs change as stories are updated. It would seem to me that this will break the integration if I rely on the current URL; it may not be the same as the created URL.
@eviltrout - are you able to comment on this?
