A reference to his profile, but no link, along with the author posting this article himself leads me to believe this was written directly to the HN community.

That being the case, why has he not addressed this broken invite issue (which was made shortly after the submission) or some of the other comments here? Why post the article if you don't have time to participate in the discussion you're trying to encourage?
