I happen to have had this item open in a window while I went for dinner, then hit "Reload" when I got back, and I noticed it's been down-voted. I wish, oh how I wish, that if someone downvotes me that they'd tell me why. Why did this particular comment not add to the value of HN? Do you just disagree? Tell me why! Do you think it's wrong? Tell me why?

I really, really would value the opportunity to learn. Even if I disagree with you, I'll still learn about the existence and content of an alternative point of view.
