RssFeedEater is a RSS Reader ( aka News Aggregator) for Windows.
It can gather information from sites that offer syndicated contents (RSS or ATOM) and presents them in a powerful hierarchical interface.

Many sites and blogs offer syndicated contents (usually a brief summary of a news or a blog entry along with a link back to the originating source for expansion) under the form of RSS or Atom files (both are lightweight XML format).
All you have to do to add a new feed in RSSFeedEater is to copy the link to these files (you can find one on the main page of this site), and then you won't need to check directly if a site or a blog has been updated because RssFeedEater will do this for you, downloading any new headlines!
