It might be worth asking viewers to share with everyone what they learned or what they disagree on (backed by a counter argument). We are a bunch that likes to learn from other people's opinions and engage in interesting discussions.

Whenever I introduce someone to HN I make sure to lay down the rules of the land first and when I come across comments like the ones below I usually try to engage them more rather than vote them down.

Not that it really matters at this point, but I didn't come here from Andrew's site to comment on this link specifically, but I had watched it earlier in the day and came across it here completely randomly.

For the record, I posted my comment before Andrew added the HN link to the article. It had no bearing on my comment.
