Many thanks to you as well as wycx, cperciva, and mirimir for engaging in the conversation. I learned a few things from you all! I must confess: after my initial comment started gathering downvotes I was on the verge of deleting it. I'm glad I didn't, since it led to such an interesting and informative discussion. I've seen this fairly often on HN, where someone posts a comment that is either factually wrong, off topic, or just something I strongly disagree with, and then a very interesting conversation follows from that. I make a point of upvoting the original comment along with the replies, since after all it was that comment that sparked the discussion.
