There was an article[1] yesterday where a single poor word choice derailed much of the comment section with rat-holing and nitpicking until the author revised the article. HN's gotta HN.
If you're talking about the use of the word "hover", I think that was quite justified, given that it was a critical element of the claim, and the poor wording made it neigh impossible to reproduce the author's claim.
