What I do, is if I want to save a page because of the great discussion, I use the "print w/replies" link to get a nice page (without the chatterbox clutter), with the node_id at the top, so you can point others to the page as a url link. Then I locally save that page and put it in a catagorized directory of "doc's" which I keep.

My only complaint, is ( on linux at least with Mozilla), these pages all come up with a name "index.pl.html" when I go to save them; requiring me to give a descriptive name of my own to the html file.
