StumbleUponStumbleUpon is a great free website that allows users to rate a site they like or don't like by clicking a thumbs up or thumbs down icon. It is made possible by using a free add-on, available through the company's website. With thousands of active users, you can view the most highly rated sites in categories that interest you. On StumbleUpon you can also visit other users' pages and view their "Stumblers" — items on the Internet they've found interesting. You can also send messages, make new friends, and much more.

Tip: We highly recommend this site and service to users who're looking for something to, or just want to surf the best places on the Internet.
