In April, I mentioned that NetNewsWire added support for syncing feeds with NewsGator. This allows you to read a post with with either NetNewsWire, or NewsGator, and have the read status reflected with the other.
NewsGator has a view of the feeds that is meant for use on mobile devices. NewsGator Mobile works pretty well on my cell phone. There is one thing that I would love to see added. I would like to be able to mark posts so they can be read later with a more capable interface.
