I think you're misunderstanding the point of the guideline. In set theoretic terms, "good hackers" are a subset of "anyone". Thus, something that's interesting to anyone is by definition interesting to good hackers as well, and is therefore fine. The problem arises when there are too many submissions that are not interesting to good hackers. That's what keeps this community from becoming just another StumbleUpon or Digg or /r/news. If it's not interesting to most "good hackers", it's off topic. If it's interesting to "anyone", to include "good hackers", then it's fine.
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.
