I use NewsGator for Outlook at work to manage and read my feeds. I use Outlook at home for my personal mail but have never gotten around to installing the client at home as well. Supposedly NewsGator will sync the items that I have read so that I can read from both home and work clients and not have to wade through items that I have already read at one place or the other.
One interesting feature that I noticed in this newer version that I have installed at home tonight (mine at work is at least 9 months old), is the ability to post to blog APIs. Even reference posts that I am reading in my feed lists automatically. This could be really cool if it works well and am planning on giving it a shot. This would be my first post from Outlook (it’s just like writing an email so far).
