What Are RSS feeds?
Really Simple Syndication (RSS) is an XML-based format used for content distribution and syndication. Subscribing to RSS feeds allows you to receive custom, up-to-date information from your favourite online content sources without having to regularly check the site for updates.
How to Access RSS feeds
You can view RSS feeds using news readers that display RSS feeds from the websites you specify (they usually display an orange icon to click on, see above) . They check the RSS feeds you have subscribed to and display new items from each feed. You can download news reader applications for your computer, and here are also many popular web-based news readers available, such as Google Reader and Bloglines. Some web browsers and email applications also have RSS capabilities built in.
Note: Google Reader is being ‘retired’ by Google in July, see post above.
