I can't get enough of this Firefox extension, Stumble Upon . Stumble Upon is like channel surfing but for the world wide web. It selected sites suited to you and your interests based on what others of similar intrest have provided.

If you like stumble upon and want to add me as your friend you can find my stumble upon page here: http://crazy675.stumbleupon.com/
