Feed Reader or News Aggregator software allow you to grab the RSS feeds from various sites and display them for you to read and use.
A
variety of RSS Readers are available for different platforms. Some popular feed readers include
Amphetadesk (Windows, Linux, Mac),
FeedReader (Windows), and
NewsGator (Windows - integrates with Outlook). There are also a number of web-based feed readers available.
My Yahoo,
Bloglines, and
Google Reader are popular web-based feed readers.
Once you have your Feed Reader, it is a matter of finding
sites that syndicate content and adding their RSS feed to the list of feeds your Feed Reader checks. Many sites display a small icon with the acronyms RSS, XML, or RDF to let you know a feed is available.
