Fav.or.it is a new kind of RSS aggregator, somewhere in between a pre-set collection of feeds like Alltop and a full-on Google Reader-style service. It had been in closed beta, but now's it's opening to everyone. It includes a set of 2000 of the most popular and interesting feeds, and provides recommended stories based on what you're reading, how long you spend on it, and how you rate it. Basically, Fav.or.it tries to pay attention to what you're paying attention to. Also, as we reported earlier, your comments show up in Fav.or.it and on the original story.

It's no reason to abandon Google Reader, but if you're not already reading RSS feeds, this is a good introduction to managing them. With it's Top-Story-focused, categorized startpage, it reminds us more of Google News than Google Reader in some ways. Whether Fav.or.it gets a good user base is going to be depend on how happy people are with its recommendation algorithm. Even if you just think of it as site that exposes newbies to a couple thousand top blogs, it's doing a useful service for the Internet.
