News Groups


News groups have largely been replaced with other methods of
discussion and dissemination of information



When news groups were common news servers existed at most ISP
or large sites and would distribute new articles to other remote
news servers



Messages are in groups
and moderators control
the content (and the
flames)



Google has a cache of the
most common news
groups



Online Chat


Internet Relay Chat (IRC) was one of
the most common forms of online
chat


Multiple servers connecting together
to allow users to participate in large
forums



IRC is still alive and well



IRC chat now is often used for more
dubious tasks now (e.g. controlling
botnets
)



Need a client to connect to the IRC
servers (
mirc

is a widely used client)

Instant Messaging


Instant messaging (IM) allows users
to exchange immediate short
messages (or files) with their friends



As simple as phone call (or SMS) to
make



Must add friends



Online friends appear in your contacts
list where you can send messages to
them



Some IM services can be accessed
from cell phones

Like IM is to email,
twitter is to blogging


For quick updates


Followers are notified of
your updates



One can update a line or
two to a webpage on the
twitter site and followers
are notified of that
update


Updates can be a phone
or desktop app
