Shrook 2, and OS X RSS/Atom reader, looks very interesting. The Smart Group feature is very nice. Similar to Smart Playlists in iTunes. For example I just set up a Smart Group to track all the Lewis Elementary site feeds. Can set up SmartGroups to track just about anything. Also it will load my feeds on my iPod. Not that I plan to read RSS feeds on my iPod, but just the idea is pretty interesting.
