An RSS file is a list of headlines that can be read by another program or website. RSS is usually said to stand for "Really Simple Syndication" because it is relatively easy to implement and use.
Programs that know what to do with RSS files are called "news aggregators," and there are a lot of them. Most are very easy to use. They all let you read headlines from dozens or hundreds of news sites at one time.
There are three kinds of aggregators: aggregator web sites, web browsers that act as aggregators, and stand-alone aggregator software that you install on your computer. Once you have an aggregator, simply click on the RSS icon ( ) associated with any of the feeds below. It will take you to a page where you can add the RSS feed to the most popular aggregators with one more click.
