The value, in my opinion, comes from the fact that
SearchEngineLand broke the story. The original Google post is extremely low key, as one might expect given that previous versions of the document were leaked not released with an accompanying announcement.
As best I could tell, no other outlet had covered the document release before SearchEngineLand nor had anyone submitted the original to HN.
As an aside, what else can one expect visually from a site devoted to SEO?
YMMV.
