XNA redux

I am surprised and somewhat disappointed that the discussion of the pros
and cons of XNA didn't generate more signal (as opposed to noise, or light
to heat) in this group -- but somehow it - the discussion - got off to a
bad start by muddying the xna issue with the 'issue' of nyms. While both
nyms and xna can relate to privacy, the basis for the use of each seems
distinctly different to me.

The most important/significant usage of XNA expiry (IMO) is by GG^3
because it is the 'biggest' and most used archiver. GG's usage springs
from the DejaNews archive usage^1 where the XNA was (more or less)
invented or originally implemented. The concept of an expire line
predated deja's XNA, and gmane has a more comprehensive discussion^2 of
the various archive/expiry lines than does GG. Naturally respect or
treatment of xna or other expiry lines is completely up to the archiver.
And then there's the consideration of webforums not GG which leech from
usenet.

It seems reasonable to ask an XNAer what is the main 'reason' or intent
s/he chooses to do so without assuming that the main reason a person uses
XNA is the same as the reason that a poster may choose to use a usenet nym
or handle only without disclosing a meatspace identity. After due
consideration of XNA, maybe more people and/or maybe less people would be
influenced to use or not use XNA regularly, sometimes, or never.


http://en.wikipedia.org/wiki/X-No-Archive Use of X-No-Archive began when
DejaNews debuted in early 1995. -- a number of regular newsgroup
participants were concerned about privacy rights, as well as the
possibility that their messages could be re-posted through DejaNews at
some point in the future.

http://gmane.org/expiry.php Gmane respects the X-No-Archive, Archive and
X-Archive headers. These headers allow users to say how long Gmane should
store messages. - Gmane implements expiry with cancel messages. - cancel
messages result in the messages disappearing from both the news and web
interfaces, but the messages won't really be deleted.

http://groups.google.com/support/bin/answer.py?answer=46487&topic=9253 To
prevent a message from displaying after the usual seven days, or from
being searchable on Google Groups after being removed, make sure it
contains the text 'X-No-Archive:' either in the message header or as the
very first text in the first line of the message body.
