I've been using Newsgator for outlook for a while now. Scoble however posted today a correction about another aggregator thats out and aout so I decided to take a look at it. I'm impressed with it so far - Integrates with IE and Firefox to give you the ability to subscribe without having to open up Outlook or fire up a website, intergrates with del.ico.us so you can tag and stuff. It also so far is updating feeds faster and more accurately - its in public preview at the moment but you can get it here: http://www.attensa.com/products.php I'm considering replacing Newsgator with this. Enjoy!
