There are many kinds of RSS readers out there. I’m partial to a web-based service called Bloglines. I used to love my desktop application (or Windows-based) reader called SharpReader, but just like using the web better. There are others that are browser based like live bookmarks in Firefox.
Then there are those that run inside Outlook. My buddy Jeff has given a review of Attensa RSS Reader for Outlook.
I may need to check this reader out sometime. I live in Outlook and it makes sense to get feeds in there.
