From Keith Bowes:
R3R is a command line RSS feed reader for Windows. It supports standard RSS 0.9-2.x and Atom feeds and the lighter RSS 3.0 (whence its name) and ESF formats. The modular design allows easy adding of new formats and user interfaces. R3R comes with several RSS feeds added by default. You can add your own feeds to it by hitting "g" on your keyboard.
