Cluztr lets you discover new sites and keep track of old ones you´ve checked out and loved without the use of bookmarks. Instead of creating a list of individual sites that you add content to, Cluztr automatically keeps track of your browsing activity and stores it for you and your friends to check out and refer back to. With Cluztr, you can keep track of where your friends are surfing online so that you can meet up and follow their trail, checking out what they´re paying attention to.
