Symbaloo is an online visual bookmark organizer. You can use it as your start page and see all of your favorite sites in a format that is easy to view.
The page is set up as a series of "tiles" and you can drag and drop links in as a new tile and then visualize that site by its icon or logo. It's much easier to use than the favorites bar built into your browser. Not only can you bookmark your favorite sites here, you can also access various other useful web tools.
