Because I didn't reference anything that wasn't mentioned in the post of the article. I brought in no outside facts. It's not my job to bring you up to speed on a discussion that I'm not even digging beyond the main article into with my comments.
You asked me to do something and I have no interest in doing that. Instead of just accepting that I told you no you're snarkily "I just asked you a simple question"-ing me. I don't have to, just move on with your day.
okay.
perhaps in the future you might consider writing a blog, instead of comments on HN, so that other people wont disturb you.
