I got an invite to Toluu.com Cool site. It basically just collects a list of your RSS feeds, and compares it to other people's (especially your friends on the site), and let's you find other blogs that might interest you. Useful and simple. You can import your feeds from your reader (using OPML), so you don't have to type things in individually.

Definitely a cool site that does something useful. Below is a link to my Toluu page, and I also added it to the sidebar.
