This kind of thing was discussed quite exhaustively in news.future last
year, and one of the spinoffs was an actual software implementation
which is currently available via ftp. I haven't kept up on it so I
don't know whether it can be used for mailing lists at the moment,
or just for "virtual" newsgroups, but in any case I include three
items of info below.
The first is a finger message from last summer that gives an overview,
the second is an equally old alpha-test message from the primary author
that gives more info, and the third is a recent ftp site announcement from
him. Between the three you should get some notion of what strn
is all about and whether it's worthwhile following up on.
If it does not currently support email lists, perhaps the authors could
be persuaded to add such support. There's also a mention of public
key cryptography below which is somewhat interesting.
Since his address changed over the last 6 months, I took the liberty
of changing references from his old to his new address in the older
two items, to avoid confusion.

Plan:
STRN/USENET Interface Project.
The strn (Scan/Scoring Threaded ReadNews) program will be the
first software release of the USENET Interface Project.
Strn consists of two major (and some minor) additions to the trn program
(version 3.0) by Wayne Davison/Stan Barber/Larry Wall. The additions
are over 10000 lines of C code which implement newsgroup selection
menus by user-defined "topics", an interactive article selection mode,
and fast methods of scoring articles with prioritized display and
commands similar to KILLfiles. An interactive multi-level
documentation browser is also being developed.
USENET Interface Project:
-------------------------
The purpose of the USENET Interface Project is to
identify and implement methods of dealing with "human bandwidth"
problems of USENET. Its goal is to allow users to be presented with
the articles they wish to read in the order they wish to read them,
without restricting the posters of articles. There are currently three
stages planned:
1. Filtering/Prioritizing
Given the articles which currently exist, delete the articles
which the user is unlikely to read and present the remaining articles
in the order of their priority (score). This builds on and enhances
the currently existing mechanisms such as separate hierarchical
newsgroups and KILLfiles.
2. Suggestion/Addition
Adds more information to make the filtering/prioritizing
process more accurate (accuracy is measured by how well the presented
order matches the user's wishes). Rating services may replace
moderated newsgroups, where individuals decide which rating services to
follow and what level of quality is acceptable. Summarizing and
keywording services can also be made available to allow better
selection and prioritizing. This stage will introduce problems in
distributing the additional information and security (especially since
the reputation of moderators may become much more important).
3. Alteration/Change
The basic idea of this stage is that what the contents of the
original posting are only a suggestion of what the reader will
eventually view. While the original text would be propagated
unaltered, various people would propagate their suggested editorial
changes (such as hypertext links, spelling or factual corrections,
moderator's notes, or summaries). What a reader finally views would
be the combination of the original text with the changes of trusted
editors. Another possibility at this stage would be the "virtual
newsgroup" which is simply a collection of articles chosen by
moderator(s).
Send me email for more information on any of these projects.

Newsgroups: news.future
Subject: Virtual newsgroups, ratings, indexes--coming soon?

Message-ID: <[email protected]>
The recent discussions on news.future have been very
interesting. I'd just like to add that I'm working on several ideas
similar to some recent posts, and I hope to have some useful results
in the near future. For instance, strn is very close to supporting
"virtual newsgroups" consisting of arbitrary articles from arbitrary
newsgroups. These could be things like "top 20 thread" lists, indexes
similar to alt.sources.index, or moderated subsets of existing groups.
In the next release strn (Scan TRN) will have merged newsgroups
consisting of all the articles from a set of newsgroups presented together.
(The code works well, but it needs documenting before release.) Virtual
newsgroups are a fairly easy addition to this which I hope to add next week.
Distributing virtual newsgroup lists is going to be the hard part.
For now I'm looking at a mailing-list approach. (Ick--I hate mail filters.)
(Distributing the information using an alt.group with public key
authentication would be easy. Unfortunately, that doesn't seem
possible in the current political environment. Anyone who knows
differently is *welcomed* to correct me. Even weak authentication would
be welcome if unpatented and exportable.)
In short, some of these schemes might be implemented a few months
from now. I hope to release strn 0.9.0 (beta) in a "few" weeks--right
now the alpha testing list is semi-closed. (You *might* be able to
convince me if you try really hard.) I'd like to talk to people about
new ideas, but I believe that the implementations are more
important--USENET isn't about to run out of new ideas anytime soon. ;)

Newsgroups: news.software.readers,news.future
Subject: Strn version 0.9.2 is now available.
Date: 21 Jan 1994 15:45:57 -0500
Organization: Express Access Online Communications, Greenbelt, MD USA
Keywords: strn, newsreader, filtering, prioritizing
[I thought some of the news.future crowd might be interested in some of the
new developments, especially Internet-sharable virtual newsgroups.]
Strn (Scan TRN) version 0.9.2 is now available.
See below for FTP sites. [Some of the uunet mirrors might take a day or
two to get a copy.]
Strn is based on trn (version 3.4.1 by Wayne Davison), and
contains all of the trn commands and features. It adds many new
capabilities to trn, such as a newsgroup browser, virtual newsgroups,
scoring/rating of articles, and easy configuration menus. Strn has
been developed and tested over the past year with the help of more
than 50 alpha testers. The beta release is intended to make the
current version more widely available, test out some of the new
concepts (such as index-moderation using virtual newsgroups), and
gather suggestions for improvement.
Strn is still under development, although most of its planned
features are implemented. Future versions of strn will mainly improve
the documentation, scoring ease-of-use, and configurability of the
program. Version 1.0 release is expected in a finite amount of time.
Outline of major strn features:
* The "scan mode" interface
o A consistent full-screen interface for the four scan modes.
. Implements many common commands such as movement, shell escapes,
and searching.
. Common code allows quick development of new scan modes.
o Uses arrow keys for movement (trn-style 'n' and 'p' are also allowed).
o X windows mouse selection (when strn is run under "xterm").
* Group scan mode
o Full-screen interface for newsgroup selection.
o Can replace the trn newsgroup selector for most purposes.
o Easy subscription/unsubscription to newsgroups.
o User-definable and sharable topic hierarchies.
. Example: one could have an "IBM PC" topic containing
the groups in comp.sys.ibm.pc.*, comp.os.msdos.*, comp.os.os2,
and comp.os.ms-windows.*
o Topic hierarchies can be easily shared:
. Locally, by adding a link to another user's topics.
. Remotely, by sending the topic files to other users.
. Via Internet using Uniform Resource Locators (URLs).
* Virtual scan mode
o Supports "virtual groups" consisting of articles from any newsgroup.
o Supports an easy-to-use "hotlist" of selected articles.
o Merged groups, such as rec.arts.sf.* (all articles in those groups)
o Virtual group files can be mailed to other users, and (with some setup)
automatically added to a user's virtual group files.
o Posted virtual group files can be used directly, allowing easy
"index-moderated" newsgroups.
o Virtual newsgroups can be shared via Internet and URLs.
* Article scan mode
o Subject-based "threading" available.
. All articles with the same subject can be displayed as one line.
o Summaries and keywords can be displayed.
o Articles can be marked and read as a group.
o Displays articles in either arrival or score order.
(See below for more information on scoring.)
* Scoring
o Articles are assigned a score by scoring rules consisting of:
. Header matching: either exact text or regular expressions.
. (optional) NewsClip programs.
o Scoring allows high scoring (interesting) articles to be presented
before non-scored (ordinary) or negative-scoring (uninteresting) ones.
For instance, in sci.space, one could give higher scores to
postings from NASA or JPL, and easily read only those articles.
o Articles are graded on a continuous scale, rather than a binary
keep/junk distinction. (Articles scoring below a threshold
value can be junked automatically.)
o Scoring is *fast*, typically limited by I/O times to fetch article
headers.
o Scoring rules can be entered with an easy-to-use menu.
o Scoring can be done from a shell script run by cron/at.
o Scores are saved to a file so they don't need to be recalculated.
* Online help (help scan mode)
o Typing 'H' at almost any prompt enters help scan mode.
o Help scan mode presents menus of documentation, containing:
. The complete trn manual, broken into sections.
. Full strn documentation.
. Introductory USENET documents (such as "What is USENET?").
o Help files can be easily edited by the local administrator.
* Online configuration
o Easy menu-based configuration of almost all strn options.
o Accessible from the newsgroup selector or group scan mode.
o Configuration changes are automatically saved for the next strn run.
o Site-wide configuration
