This site provides a way to connect with other people who use Google Reader. You can find people who share similar tastes, and even get a feed of recommended articles. The aggregation of our shared items feeds allows us to see what blog entries/articles/items are the most popular. (Some of these features are still coming soon...)
Sign up today!
If you've got some friends using the sharing functionality of Google Reader, you can enter their feeds on your page as well, and see their shared items along with your own. (and they don't even have to sign up yet...)
