Just asking why. Why submit it. There's nothing new on it. We're just repeating the same discussions had before that can be read on the previous discussion when it was new. Hence linking to the other discussion thread.
As I said above, what is new is "me", the audience, and imho that's reason enough. I will never start digging around like a mad man in the annals of HN for cool stuff to read, but if some good older piece makes the front page again, then that is good.
