If you are not one of the more than 12 million people who have discovered StumbleUpon, this is a site that describes itself as a “discovery engine that finds the best of the web, recommended just for you.” Whether through Facebook and Twitter friends, people that you subscribe to or people who subscribe to you, it combines social interaction with the sharing of websites by people who have similar interests.
The aim of StumbleUpon is to help users find content on the Internet that they may not otherwise have discovered using a traditional search engine. As you “stumble,” you will see only websites that have been recommended by friends and those of a like mind, which means that you come across only content that is relevant and interesting to you. Based on a ratings system, the site uses the collective opinions of members as well as “machine learning” to offer up relevant content, and ratings are also used to connect people with similar interests. As members interact and share their favorite sites, each one benefits from an improved web surfing experience. In addition, as StumbleUpon learns about the things you like, the content that it offers becomes increasingly relevant.
According to StumbleUpon’s CEO Garrett Camp, 500,000 new members are joining the site each month, so if you are not a member already, sign up now and choose from among nearly 500 different topics to indicate your own personal interests and preferences.
