StumbleUpon is a new way to surf the web. It lets you channel-surf pages recommended by friends and peers – great sites you can't find using search engines.
We are a community-based, word-of-mouth approach to websurfing - pages you "stumble upon" come from like-minded people who share your interests. Add the Toolbar, choose some topics and click Stumble! You'll meet people who like your favorite sites as you discover the best of the web.
