That’s definitely barking up the right tree, but this bit might be a problem at first glance:
If you set this up correctly, the first time you visit http://example.com/blog/entry-123.html it will try to load comments for the blog post. Since there are none, it will tell the Discourse forum to create a new topic in the background. A new topic will be created by eviltrout and the contents of the first post will be crawled from your blog and the text will be extracted automatically.
That means that the topic will be created in Discourse when the first person opens the article? For Coding Horror that’s fine because I doubt there has ever been a Coding Horror blog article that’s not generated comments.
I’ll read the rest of the instructions later as I appreciate, this might be covered later.
