RSS (Really Simple Syndication) is a simple way to get news from your favorite sources. Rather than visiting all your favorite websites to check for new information, you "subscribe" so that news is delivered to you as it is published.
The most common option for reading RSS feeds is to use a RSS news reader or aggregator. Two popular, free ones are Google Reader and Bloglines; no downloads are needed but you must register. Find many more options through Yahoo.
The method for subscribing to a feed can vary somewhat depending on the particular reader you use. Usually you simply click on the orange RSS or XML button, copy the feed's URL from the displayed page, and then paste it into the reader.
Note: Internet Explorer browsers may display code in place of RSS content.
To correct this, change the RSS settings. On the IE menu bar, select:
Tools > Internet Options > Content [tab] > Feeds (Settings) > Check "Turn on feed reading view"
(IE6 and previous versions cannot display RSS feeds.)
