The GreatNews RSS reader's straightforward layout emphasizes easy
sifting through the many, many posts you can collect as you add
more news feeds. The lightweight download doesn't pack in a huge
number of features, but you can choose from six different reading
styles, including Newspaper, Essay and Firefox Sage, to find the
one that suits you best.
You can easily import your OPML feed lists into GreatNews and
export them back out again, so it's easy to try it and other
readers until you find the perfect match.
