Hmmm, reading the HN guidelines I find that I am encouraged to post anything that piques my intellectual curiosity. I ignore almost all articles about US politics (I'm a Canadian), but this one was interesting because of the discussion about body language, and most especially interesting because of the implications of never admitting your political opponent is correct in a negative-style campaign.

That's an interesting aspect of game strategy, which seems to tickle the same part of my brain as many other things I associate with hacking. Well, now you have my explanation as to why I feel posting this complies with the HN guidelines.

Now, help me out: What's your explanation for posting a comment complaining that something isn't hacker news, something specifically discouraged in the guidelines???
