- "Ideal conversation must be an exchange of thought, and not, as
- many of those who worry most about their shortcomings believe,
- an eloquent exhibition of wit or oratory." -- Emily Post, Etiquette

-
- Imagine a conversation carried out over a period of hours and days,
- as if people were leaving messages and responses on a bulletin board. Or
- imagine the electronic equivalent of a radio talk show where everybody
- can put their two cents in and no one is ever on hold.
-
- Unlike e-mail, which is usually "one-to-one," Usenet is "many-to-
- many." Usenet is the international meeting place, where people gather to
- meet their friends, discuss the day's events, keep up with computer
- trends or talk about whatever's on their mind. Jumping into a Usenet
- discussion can be a liberating experience. Nobody knows what you look or
- sound like, how old you are, what your background is. You're judged
- solely on your words, your ability to make a point.
-
- To many people, Usenet IS the Net. In fact, it is often confused
- with Internet. But it is a totally separate system. All Internet sites
- CAN carry Usenet, but so do many non-Internet sites, from sophisticated
- Unix machines to old XT clones and Apple IIs.
-
- Technically, Usenet messages are shipped around the world, from
- host system to host system, using one of several specific Net
- protocols. Your host system stores all of its Usenet messages in one
- place, which everybody with an account on the system can access. That
- way, no matter how many people actually read a given message, each
- host system has to store only one copy of it. Many host systems "talk"
- with several others regularly in case one or another of their links goes
- down for some reason. When two host systems connect, they basically
- compare notes on which Usenet messages they already have. Any that one
- is missing the other then transmits, and vice-versa. Because they are
- computers, they don't mind running through thousands, even millions, of
- these comparisons every day.
-
- Yes, millions. For Usenet is huge. Every day, Usenet users
- pump upwards of 40 million characters a day into the system -- roughly
- the equivalent of volumes A-G of the Encyclopedia Britannica. Obviously,
- nobody could possibly keep up with this immense flow of messages. Let's
- look at how to find conferences and discussions of interest to you.
-
- The basic building block of Usenet is the newsgroup, which is a
- collection of messages with a related theme (on other networks, these
- would be called conferences, forums, bboards or special-interest
- groups). There are now more than 5,000 of these newsgroups, in several
- different languages, covering everything from art to zoology, from
- science fiction to South Africa.
-
- Some public-access systems, typically the ones that work through
- menus, try to make it easier by dividing Usenet into several broad
- categories. Choose one of those and you're given a list of newsgroups in
- that category. Then select the newsgroup you're interested in and start
- reading.
-
- Other systems let you compile your own "reading list" so that you
- only see messages in conferences you want. In both cases, conferences
- are arranged in a particular hierarchy devised in the early 1980s.
- Newsgroup names start with one of a series of broad topic names. For
- example, newsgroups beginning with "comp." are about particular computer-
- related topics. These broad topics are followed by a series of more
- focused topics (so that "comp.unix" groups are limited to discussion
- about Unix). The main hierarchies are:
-
- bionet Research biology
- bit.listserv Conferences originating as Bitnet mailing lists
- biz Business
- comp Computers and related subjects
- misc Discussions that don't fit anywhere else
- news News about Usenet itself
- rec Hobbies, games and recreation
- sci Science other than research biology
- soc "Social" groups, often ethnically related
- talk Politics and related topics
- alt Controversial or unusual topics; not
- carried by all sites
-
- In addition, many host systems carry newsgroups for a particular
- city, state or region. For example, ne.housing is a newsgroup where
- New Englanders look for apartments. A growing number also carry K12
- newsgroups, which are aimed at elementary and secondary teachers and
- students. And a number of sites carry clari newsgroups, which is
- actually a commercial service consisting of wire-service stories and
- a unique online computer news service.
-
- ... With so much to choose from, everybody will likely have their own
- unique Usenet reading list. But there are a few newsgroups that are
- particularly of interest to newcomers. Among them:
-
- news.announce.newusers This group consists of a series of
- articles that explain various facets of
- Usenet.
-
- news.newusers.questions This is where you can ask questions
- about how Usenet works.
-
- news.announce.newsgroups Look here for information about new or
- proposed newsgroups.
-
- news.answers Contains lists of "Frequently Asked
- Questions" (FAQs) and their answers from
- many different newsgroups. Learn how to
- fight jet lag in the FAQ from
- rec.travel.air; look up answers to common
- questions about Microsoft Windows in
- an FAQ from comp.os.ms-windows; etc.
-
- alt.internet.services Looking for something in particular on
- the Internet? Ask here.
-
- alt.infosystems.announce People adding new information services to
- the Internet will post details here.
-
- -----
-
- And now for a few words from "p-crispy-one":
-
- The EFF (1) notes that daily input into Usenet is equivalent to volumes
- A-G of the Encyclopedia Britannica. You should be warned that the
- information on Usenet is of *much* lower quality. Anybody with an
- opinion can post anything in a Usenet newsgroup, whether they know
- what they're talking about or not. If you want to bet your grade
- in school or your company's or organization's future on information
- you get from Usenet, please e-mail me first -- I have some bargains
- in real estate (including a great price for a bridge in Brooklyn) I'd
- like to discuss with you.
-
- There are more Usenet newsgroups, dedicated to the discussion of more
- topics, than you could even imagine. I recently heard that there are
- over 6,000 different Usenet newsgroups, although I think that number
- may be a little low. The Osborne/McGraw-Hill Internet Yellow Pages
- has fifty-five pages of Usenet newsgroup listings (p. 363-418).
-
- What are some of these newsgroups? Here is a short list taken from
- the Osborne/McGraw-Hill Internet Yellow Pages (and reprinted by
- permission):
-
- alt.abuse-recovery Helping victims of abuse recover
- alt.barney.dinosaur.die.die.die Hate and excoriation of Barney the
- Dinosaur
- bionet.jobs Job opportunities in biology
- bit.listserv.xerox-l Xerox products
- biz.books.technical Selling and buying books
- clari.biz.top Top business news
- comp.cog-eng Cognitive engineering
- ...
-
- As you can see, the topics are pretty diverse. I also want you to
- notice something about the group names. All of the Usenet group
- names have periods (or, in Internet language, "dots") in them.
- That is a great way to see if a group is a Usenet group or a
- mailing list group (which we covered last week).
-
- GROUP TYPE
-
- gnu.emacs.sources Usenet newsgroup
- RHA-L Mailing list
- rec.birds Usenet newsgroup
- Navigate Mailing list
-
- So, how do you read the posts in a Usenet newsgroup? Well, you have
- to have access to a Usenet newsreader.
-
- There are literally DOZENS of different Usenet readers out there.
- Your local Internet provider will be able to tell you what Usenet
- reader you have access to, and will probably also be able to
- tell you some of your reader's commands (remember that in a lot
- of Usenet readers the commands are case sensitive).
-
- Some of the more important Usenet reader commands that you need
- to know are:
-
- - How to access your Usenet reader
-
- - How to access a particular newsgroup
-
- - How to subscribe/unsubscribe to a particular newsgroup
-
- - How to read a post
-
- - How to send a post
-
- - How to respond to a posting by e-mail
-
- - How to save a post
-
- - How to move from one newsgroup to another
-
- - How to exit your Usenet reader
-
-
- HOMEWORK:
-
-
- 1) Ask your local Internet service provider if you have Usenet
- access. If you do, ask your provider for a handout or
- help file which lists the commands for your reader.
- (Most Usenet readers also have a pretty extensive, albeit
- confusing, help screen. If you can get into your reader,
- you may want to check out this help screen).
-
- If you don't have Usenet access, or if your provider does
- not have a help file, please be patient. When we get to
- the lessons on Gopher (in about 2 weeks), I'll show you
- some tricks that will help you around this problem :)
-
- 2) If you have access to either the rn or nn newsreader (two of
- the most used newsreaders around), I have two files that may
- help you. Again, use the get command to get them from the
- LISTSERV file server at University of Alabama.
-
- nn users: rn users:
- filename filetype filename filetype
-
- nn intro rn intro
- nn cmds rn cmds
