How do you feel if one of your knowledgable friend is sitting near you whenever you like to surf on the web and helping you by pointing-out some good, informative websites of your interest?

A social book marking site StumbleUpon helps you to discover new websites of your own interest. Also you can mark a website that you know or currently browsing and share with your friends. The site supports rating of websites that you are viewing.

Stumble Upon

When people mark and rate the sites that they view these sites get appreciated by the community so that others can know about the quality and popularity of them.

StumbleUpon offers nearly 500 topics which users may choose to indicate their interests and preferences so each Stumble produces only the most relevant content. StumbleUpon delivers increasingly relevant content as the Toolbar learns what the user has liked in the past and continues to present quality web sites in the future.

Using a combination of human opinions and machine learning to immediately deliver relevant content, StumbleUpon presents only web sites that have been suggested by other like-minded Stumblers. Each time the ‘Stumble’ button is clicked, the user is presented with a high quality web site based on the collective opinions of other like-minded web surfers.

Information on the Internet changes rapidly. StumbleUpon is a dynamic approach to keep on top of this ever-evolving pool of knowledge. StumbleUpon filters through the vast amount of information on the web to direct Stumblers to high quality web sites which are relevant to their personal interests. An obscure but interesting site can be immediately shared with other like-minded users. Old or low-quality sites can be removed if their ratings become too low. The participation of community members helps maintain a database of the most up-to-date and highest quality sites possible.

This is possible with the help of a tool bar. You can download and install yourself. From the following link, download and install the toolbar http://www.stumbleupon.com/download_autostart.php and enjoy your fruitful internet surfing.
