The difference is the audience.

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.

"good hacker" is a subjective term and an obvious True Scotsman. It might as well mean nothing more than "your interests correspond to the interests of the moderators."
