Apple Mac OS X Server v10.6 - Manual (Page 54)

Traditionally, when someone updates a document, they attach that document to
an email or upload it to a website and notify everyone that the document has been
updated. RSS simplifies and streamlines this process by notifying people when
content changes.
Whenever anyone—not just the original author, changes a page, anyone who’s
interested in the page will have it in an RSS feed and will be notified that it’s changed.
They can review the changed content, and refine it further without notifying everyone
that they’ve changed the content again. RSS helps people focus on content and
reduces the amount of time spent notifying people who might not be interested in
the content thats changed:
Original author creates page
Original author sends out email notifying
everyone of page location and RSS feeds
Group member reads page
Group member changes the page
RSS notifies everyone
