Well you just said it: "Anything that good hackers would find interesting" and not "Anything that anyone would find interesting".
Oh wait.. /s
I said it IS interesting ... to anyone.
You see the content drive the audience and then the audience drive the content.
Too much broad interesting articles and it's not Hacker News anymore.
While I found this article interesting in itself, it's something that can be interesting to anyone, regardless of its background.
While harmless at first look, this can be an issue if too many content fall into this category.
Then you end up with a reddit clone instead of HackerNews. I'm here to see hacker news, not interesting stuff for anyone.
