https://hn.algolia.com/?q=research+goblin it's like the third time it gets posted and only got traction because I asked why it's popping up in the new q over and over again.

The original author submitted it, then when it didn't get traction it looks like two fans of his blog both submitted it around 12 hours later. Whether for internet upvote points or because they personally thought the article particularly great, I don't know.

Personally I generally enjoy the blog and the writing, but not so much this post. It has a very clickbaity title for some results which aren't particularly impressive.
