RSS (Really Simple Syndication) is a popular means of sharing content (such as news headlines) without requiring readers to constantly visit a Web site to see what's new. RSS feeds contain headlines and hyperlinks to longer articles or Web pages.
In order to use RSS, you need to download and install RSS reader software, also known as news aggregator software (see CNET's or Wikipedia's lists). Alternately some browsers, including Internet Explorer 7, Firefox, Opera and Safari, have functionality that automatically picks up RSS feeds for you (for more details on these, see their websites).
Once you have chosen a news reader, all you have to do is to decide what content you want. As you visit websites, you may notice a link to an RSS feed or an image that looks like or or .
If you click on the link or button, you can subscribe to the feed. (The method of adding a feed depends on your reader.) However, if you click on one of these links without having such software installed, you will just see an ugly page of computer code.
