SpeedyMarks is a visual bookmarking site. It is very similar to the default start-up page in Safari 4.0. The way this works is by storing a "cookie" on your browser (oooh I like cookies).
I recommend checking out SpeedyMarks if you are a visual person who rather browse through pictures of thumbnails the URL links.
