What does RSS do?

RSS feeds are received as xml and are then displayed at the receiving computer in html.

Thus 'raw' xml' content looks a little like html with similar 'markup' features.

Click here http://api.edna.edu.au/headline.rss?sector=edna for an example (this may behave differently if you are using Firefox)

Sometimes you are able to use a website’s features to display an RSS feed.
Sometimes you have to pull the RSS feed in using JavaScript. More about that later.

RSS feeds may be generated by blogs. They enable the user to monitor additions to the blog

The text version of podcasts are also often available as an RSS feed.

RSS feeds thus enable the user to select sources of information and keep up to date without having to remember to visit the original website.

The source site pushes the RSS feed out, the receiving end pulls the RSS feed in.
