StumbleUpon is an intelligent browsing tool for sharing and discovering great websites. As you click Stumble!, you'll get high-quality pages matched to your personal preferences. These pages have been explicitly recommended (rated I like it) by friends and other SU members with similar interests. Rating these sites shares them with your friends and peers – you will automatically 'stumble upon' each others favorites sites.

StumbleUpon uses / ratings to form collaborative opinions on website quality. When you stumble, you will only see pages which friends and like-minded stumblers () have liked. Unlike search engines or static directories, this allows for a true "democracy of the web" – all SU members have a say ( or ) as to whether a page should be passed on.

In effect, StumbleUpon's members collectively share the best sites on the web. You can share any site by simply clicking I like it. This passes the page on to friends and like-minded people – letting them "stumble upon" all the great sites you discover.
