Like i said in my previous post, i am a syndication junkie. I've got quite a few RSS and Atom feeds in my bloglines account. However, if you are looking for an aggregator which gives MS Outlook the ability to start processing RSS/Atom, then here's RSS aggregator for Outlook. It looks a lot like NewGator, which is a paid-for software. But this is free.
I havent used it, but would sure like to know when anyone else who has.
