Browser Based RSS readers
Another breed of RSS reader can be integrated into your web browser. Since feeds ultimately link over to sites, adding a reader into your browser is a pretty good way to access feeds. As applications that get installed into your browser, these options are fairly sophisticated and usually offer significant organizational control over your feeds.
Pluck (www.pluck.com) - Pluck is a downloadable application that adds RSS capability to your web browser. It's available for Internet Explorer and Firefox (or as an online service - see below).
Sage (sage.mozdev.org) - Sage is another browser based RSS reader but it's only available for Firefox. Both Pluck and Sage are free downloads.
