RssReader This free program is for reading RSS newsfeeds. It collects news in the background at user-configurable intervals and warns you with a small pop-up in the system tray when a new message has arrived. You can click the headline to see a short description and then open the original Web page in an RssReader browser or default browser window. RSS (Really Simple Syndication) is a format for indicating news. RssReader supports RSS versions 0.9x, 1.0, and 2.0.
