I don't agree that everything here on HN is dead serious. However, the bits that are funny also add value. the bits that are funny for funny's sake are quickly down-voted, and generally don't fit with the current sense of the community.

You could've phrased your submission as:

  Don't know if people here are aware of it, but if you
  were you could've replaced that entire post with <link>

Then it would've been informative as well, and, in my experience, less likely to be downvoted.

    Now, I will go back to being my serious self ...
    Laughing is not allowed. Apparently...

HN is a multi-cultural place, and the potential for misunderstandings abounds. I've been in countries where what I thought of as a completely innocent remark has been regarded as a serious insult. I don't know how familiar you are with other cultures, but levity is frequently heavily culturally based, and getting it wrong can make you look like a complete jerk. People here usually appreciate the respectful nature of the site.

There is humor here, it's just of a different kind.
