I don't know if it seems too pedantic but I feel like it would be much more convenient to tag any posts linked to articles as such, so that people could focus in on or filter out articles at their convenience. Personally, I never read articles people post unless the subject matter greatly intrigues me, and in that case, I've read it because of reasons beyond it being an article. I think it'd be a pretty easily enforceable thing, as we have tagmods now and tagging articles (if anybody forgets) would be simple and quick.
