> This is a pretty inconsequential blog post where Gruber is just echoing another article.

He does this to amplify things, and look: it worked! The original post made the HN homepage a couple days ago, and now Gruber’s post about it has made the HN homepage again.

Amplified but redundant for HN crowd is my point. I’m not clueless as to why a person who blogs to maintain attention would amplify a topic. Your explanation was not needed.
