I'm still new to HN in general so this is probably a a rather mundane/ignorant comment - apologies - but why is this at the top of HN at the moment?

There is no content in this post, no useful points, no specific examples of what is wrong (although there is an example of how to do it right - thanks for that). No call to action other than "Do it better!".

I'm not saying it isn't worth talking about, I'm just honestly curious how the HN algorithm works that this has made it to the top. Is freshness so highly weighted?
