Indeed it would. In fact, this was the idea behind the proposed wiki pages. We haven’t really progressed with the idea, but I still think it works in principle.
One reason I haven’t pushed this idea more is because of the technical limitations of this platform for doing such work. I’d like to see support for notes and references; also tables and Table of Contents would be nice. It would be possible to hack Discourse to do these, but Discourse is in the process of moving to a new editor/markdown standard, and I want to wait until this is settled before even considering such things.
Still, there’s no reason we can’t start. If you’re interested, just start an article in the wiki category and we can go from there.
As an example of what is possible, check out this page:
They write their wiki pages on Discourse and use a custom scraper to build the structured wiki site.
