What an intersting concept. I may have to look it up now that Feeddeon trial is almost over!
One more: Feedster has come out with a web based aggregator. Scott is doing some interesting stuff over there. I track what all the blogs are saying about various things (like Longhorn, or Linux) through Feedster. Why? Because I can perform a search, and Feedster will make that search into an RSS feed that I can subscribe to. You know how you felt when you first saw a killer application? (For me, it was Pagemaker). This is a killer service. The idea that a search term can then be a syndication feed is going to change the world. You watch, if Google and MSN are smart, they'll do that for all search terms.
Feedster has dramatically changed search for me. Has it for you yet?
