And yet it was posted here and many people who know nothing of the project will read it. Writing a sentence saying what the thing is takes a few words.
It's not the job of the author to provide context for an audience they didn't even write for - but it would be HN's job to provide context for its own audience.
i.e.- this was not a rerquest or taner saner to provide context, but a request for @ericdiao to provide context.
But its especially silly to post on HN that authors need to change how they are writing in a thread on an article that wasn't posted here by the author, and where there is no indication that the author is a member of the community.
Not by the author, so I don't see how that impacts how it should be written; and HN users are free to ignore things that don't interest them, or to spend a few minutes with a search engine learning context for things that seem like they might, but which are unfamiliar (and are generally competent to both of those things as appropriate.)
