An occasional comment in another language is fine but HN is an English-language site, so people shouldn't be having entire conversations in other languages.

As a speaker of multiple languages, I disagree. There's no possibility of HN turning into a non-English language site just because a few threads are not in English; HN will always be first and foremost an English language site (and it's too long set in English for it to be anything but), and it's actually quite nice to be reminded of the existence of other conversations by other language speakers rather than only English. I and many others may not be able to participate so directly in them, but there's always Google Translate.
