Only a few example newsfeeds come with the program, so you'll need to find more on your own. Fortunately, the search box on the top of the interface helps you find RSS feeds by keyword. You also can click the Add Content Channel button and enter RSS, XML, or RDF links you find at your favorite sites; the program tells you how to do it if you need help. Unlike some readers, the viewing window offers convenient Forward and Back buttons so you can move around in pages you're reading.
Also, you can choose whether you want to view a story in the viewing window or in an external browser. Overall, we think Tristana is a great free reader for newbies who want to check out RSS.
