Display content from your favorite RSS content news feeds
RSS is a format for syndicating news and the content of news-like sites, including major news sites like Wired, news-oriented community web sites, and personal blogs. But it's not just for news. Pretty much anything that can be broken down into discrete items can be syndicated via RSS: the "recent changes" page of a wiki, a changelog of CVS checkins, even the revision history of a book. Once information about each item is in RSS format, an RSS-aware program can check the feed for changes and react to the changes in an appropriate way.
RSS-aware programs called news aggregators are popular in the weblogging community. Many weblogs make content available in RSS. A news aggregator can help you keep up with all your favorite weblogs by checking their RSS feeds and displaying new items from each of them.
When you browse the internet and see this or it should link to an RSS feed that you can subscribe to. Your web site has a built in RSS reader. To enable a page to subscribe to an RSS feed, you copy the URL of the RSS feed and paste it into the RSS Feed URL on your page editor. After saving the page the content from the RSS Feed will appear below your normal page content.
