I use NetNewsWire for all my RSS reading goodness. NetNewsWire is capable of syncing my feeds between multiple computers either via .Mac or Newsgator. I’ve always used .Mac, because the online Newsgator interface has always seemed a bit clunky to me, so I didn’t really use it.
That practice is changing today, because Newsgator has released a free version of it’s online reader formatted for the iPhone.
“The login automatically detects the iPhone. If discovered, the iPhone is routed to a version of NewsGator’s free Mobile service designed specifically to work with the iPhone, and enables users to read news feeds and mark feeds as read while they’re on the go.”
