I'm using Greed.
NewsRob is excellent, but its killer flaw is that it can't save articles beyond the previous 1000. This is a problem for me because I save articles for later reading by starring them, but only the starred articles from the past 1000 show up. I've inquired the developer about adding the feature to save ALL articles that are starred, but he was very stubborn about it and said that that was a feature he wouldn't add.
So I need to supplement NewsRob with NetaShare, an RSS reader that's almost as good. The problem with NetaShare is that it's extremely slow to sync.
