As you click Stumble! The site delivers high-quality pages matched to your personal preferences. The idea is that people can market their sites directly to their target audience instead of banners and pop-ups usually used, in a way that visitors will actually pay attention to. Rate the sites you like and automatically share them with people. This site helps you discover great sites your friends recommend. StumbleUpon.com uses ratings (thumbs up) to form collaborative opinions on website quality. When you stumble, you will only see pages which friends and like-minded “stumblers” have recommended. This helps you discover great content you probably wouldn’t find using a search engine. They can also look at other people’s reviews of the page and review it themselves. Using search engines to locate relevant content means hunting through pages of results rather than searching for quality web sites, StumbleUpon.com members are taken directly to web sites matching their personal interests and preferences.
