SS (Really Simple Syndication) feeds provide news headlines, brief article descriptions and links in an xml file that is automatically updated whenever those headlines change. This allows you to receive notification of new content in your own environment - in your browser, on your desktop, in your blog, on your website or elsewhere.
How do I use an RSS feed?
1.Via a News Reader
To view our RSS feeds on your computer, you will first need to acquire a News Reader or News Aggregator.
These programs pull all your selected RSS feeds into one place. Once you have a reader, all you have to do is: (1) click the button for the feed you want, (2) copy the URL from the address bar, and (3) paste it into your RSS application.
There are many news readers available on the web. Some can be downloaded for free, or on a free trial, while others which offer more features or customization charge. It is worth noting that some readers will work better on different operating systems. A tip is to start with a web-based application and work from there. See the links at the bottom of the page for a number of options.
2.Via a web browser
A number of web browsers, including Firefox, Opera and Safari, automatically pick up RSS feeds. Check their homepages for details. This facility is not currently available in Internet Explorer.
Mozilla Firefox browser - live bookmarks
The live bookmarks facility on the Mozilla Firefox browser allows you to view constantly-updated headlines in your bookmarks menu.
