Why archive? Because history is good. Why the anti-necroposting provision? Because if it's really relevant, having you jump through the additional hoop of quoting the good bit and copy-pasting into a new thread not only forces you to put a little bit of thought into it, but also prevents threads from being months or years (or decades) long and thus only being accessible to people who have read the whole darn thing. In my experience in Usenet, conversations go off topic remarkably quickly.
