On HN you cannot downvote someone who responds to you, so uh, that's not what is happening.

I apologize for the wrong assumption, it's just confusing why anyone else would downvote me for asking a genuine question that was also just informing the writer of the medium post about a mistake that may have confused other readers too.

Informing the author about a mistake is usually OK. But the "I had to stop reading here" line sounds dismissive and somewhat rude.

But I may also be wrong about why people downvoted you; sometimes it just seem random, so you shouldn't take it too seriously.

I didn't downvote you, but if it's any comfort I got downvoted too :)

I am however not going to change that sentence even though I know it doesn't sound (and might not even be grammatically correct) :)

You can think of it as a more open way of asking.

I.e. "where are problems hiding" it's instead of asking what is a problem" because I was trying to explore where they could be found.
