I think this is akin to posting a link to a page in a language that is not English. Surely there would be many comments reflecting the users' annoyance of having to use Google translate to read the page; no matter 'who' is sleeping or awake.
That being said, a single upvoted comment on the matter should be enough to make the OP aware.
That's the general trend I noticed on reddit. Comments about imperial/metric units are either upvoted or downvoted depending on the time (sometimes topic). Maybe HN isn't as bad. And I have to agree that one post would be enough (and comments about using search engines are not necessary).
