RSS feeds (sometimes called "Web feeds") are a way of presenting
changing content in a format that can be understood by a
computer program. A typical example would be a news site that
publishes new stories regularly. Here are some of the ways you
could use that site's RSS feed: - Live bookmarks - If your
browser understands feeds (the latest versions all do) then you
will see a little feed icon in the address bar. Clicking on it
creates a link that points to the summary (Firefox calls them
"Live Bookmarks"). Your browser regularly checks to see if a new
item has been published, and warns you in some way if it has.
You don't need to keep on visiting a page to see if anything new
has appeared on it. - Browser plug-ins - For some browsers,
plug-ins are available that can do extra things for you, such as
display a summary list of recent blog items in a sidebar. Sage
Reader for Firefox is an excellent example. - Feed readers - You
can also install self-sufficient feed readers that are
independent of your browser.
