You can go through all your news just by hitting the space bar - it's easy. Read the original Web page just by clicking a link or hitting the right-arrow key.
When you find something to save or share, you can email a link, save to Instapaper, or send to another app (such as Delibar, Twitter for Mac, VoodooPad, MarsEdit, and more).
Adding feeds is easy - most of the time NetNewsWire Lite can find a feed for a website for you, so you don't have to hunt. And you can add a feed to NetNewsWire Lite directly from Safari. NetNewsWire Lite supports authenticated feeds too, for any in-house and private feeds.
And the app is fast and light, easy-to-navigate, with just the features you need to be able to read your news.
