What do you use to keep track of your bookmarks? I just started using Diigo this summer to help me organize and share sites that I find interesting. Tags can be used to make searching for sites easier and groups can be made to share bookmarked sites with others. You can start by clicking on the image to view my profile page and then create your own account.
Symbaloo is another great organization tool. You can assign an image to a link and see your bookmarks in a visual layout.
