Ask HN: Where have all the comments gone?

I noticed the exact same thing but didn't think it was worth a post. Glad you did !

I even checked wikipedia to see if I had not missed some US Holiday.

November 13 is the World Kindness Day, but I guess it's not related. :)

Mostly people only comment on stuff that relates to them, pertains to things they care about or gets a good enough psychological reaction to comment. My opinion on the matter.
