From NewsGator Technologies:
The NewsGator Mobile RSS newsreader syncs with NetNewsWire, our newsreader for Mac OS X, and with our other products FeedDemon, InBox, Go, and our online reader so wherever you go, you have your feeds. The interface is easy to use. Just tap a feed to read it. Tap a link to open a page in Safari. Tap another button to mark all as read and go back to the feeds list. You can even clip items to save them for later.
