While my view is that if someone posted it on HN and it was upvoted high enough—it belongs there; there is little in this post that "gratifies intellectual curiosity". Unless we are talking about the child involved, but I doubt she reads HN. There is often a complaint about negativity on HN, but I don't think swinging the pendulum too far in the opposite direction adds quality. If anything it devalues really interesting content.

Intellectual curiosity doesn't only mean studying great work or deep problems. It's closely allied with a playful spirit that likes to do things just because. That playful spirit is vulnerable to being dismissed as unserious, so it needs protecting. We protect it here.

Of course opinions will always differ about any given submission, but that's the general approach.
