Time again for our Website of the Week, when we showcase interesting and innovative online destinations. Our web guide is VOA's Art Chimes.

This week it's a tool that can help you discover other websites recommended by people who have the same interests you have.

BUHR: "StumbleUpon is basically a web toolbar which helps people discover really interesting content that's out in the Web, that's highly relevant to their interest areas. And StumbleUpon helps people discover what those pieces of content are in a very engaging and entertaining manner."

Michael Buhr is general manager of StumbleUpon, where you can download a small toolbar that installs on your web browser.

BUHR: "And literally that toolbar has, on the top left-hand corner of it, a button called the Stumble Button. And all you do is press that button and we will show you really interesting websites, web content, movies, pictures, etc., that are tailored to your interest."

For example, if you're interested in astronomy, StumbleUpon will steer you to websites recommended by other users who are interested in astronomy. And you, in turn, can rate sites you visit with one simple click.

The StumbleUpon toolbar works on the popular Firefox and Internet Explorer browsers. Even without the toolbar, you can get a selection of the sites users are recommending to each other on the StumbleUpon website.

Buhr says StumbleUpon is different from search engines, which use sophisticated algorithms to steer you in the right direction. StumbleUpon adds to the mix the opinions of users like you.

BUHR: "We also rely heavily on the interests of our 4.2 million registered users, our community members, who are rating those sites up and down. So it's applying very much of a social, peer-review on top of those results."

Incidentally, 40 percent of those over-four million users are outside North America, and you can join them at StumbleUpon.com, or get the link from our site, voanews.com
