2.8 Really Simple Syndication (RSS)
RSS (Really Simple Syndication or Rich Site Summary) is a format for delivering regularly changing Web content so that it can be republished on other sites or downloaded periodically and presented to users.
One of the benefits of using RSS is that it allows users to see the latest content from sites they are interested in without having to visit each site individually. Many news-related sites, Weblogs and online publishers syndicate their content in this way as an RSS feed.
RSS feeds are assimilated by 'Feed Reader' or 'News Aggregator' software and a variety of RSS readers are available for different platforms. There are also Web-based feed readers.
Once you have your feed reader, it is then a matter of finding sites that syndicate content and adding their RSS feed to the list of feeds that your reader checks.
Many sites display a small icon with the acronyms RSS, XML, or RDF to let you know a feed is available. See RSS feeds from FAO for more information and a list of FAO feeds available.
