I have just started using NewsFire, a new Mac OS X RSS aggregator. It is a slick looking application, that really uses Mac OS X's Aqua look at feel. The author also has written Acquisition.I had been using Shrook, but it seems like it doesn't work that well if it is not able to connect to shrook.com. The one feature that I would love to see in NewsFire is the ability to mark articles.
