A social news website that brings interesting news to the front page. Some of the humor is meant more for adults but the website itself is safe for children who stumble onto it. It's a fairly simple concept, easy to navigate, usually contains entertaining and informative information about internet culture as well as important news that people vote on.
Very helpful scoring of informative and/or entertaining Web sites. With the appropriate Firefox plugins (eg. Digg FF Extension, SocialPhile, Shareaholic, etc), allows very rapid scanning of search engine results and submission of useful sites.
