I use NewsGator's Outlook plug-in to aggregate RSS feeds I want to keep track of. It's easy for me because it puts everything inside Outlook, which I already have open 25 hours of every day. I really like NewsGator. I like how it adds right-click ability in IE to subscribe to a feed. There is nothing that I really don't like about it. Simply put: it works for me.
I did decide to download and install the trial version of FeedDemon, From Nick Bradbury - creator of TopStyle, yesterday. It is sexy. I love the little “newspapers“ it puts together. It just looks good.
Now this is a product that my wife would like and would use.
I think I'll stick with NewsGator for now, but man that FeedDemon looks nice.
