Ask HN: Why do so many "Ask HN:" posts seem to cluster together?
3 comments
There's a special penalty that gets applied to Ask HN posts, I guess that's what's responsible for any clustering.
My first guess would be triggering (Person B sees a post by Person A and decides to post their own).
a. pure coincidence b. how HN ranks posts c. Some statistical correlation that exists between ask HN posts, that binds them more tightly than other posts. I would think it has to do with ask HN posts' objective: to be answered. d. total fluke just my experience
