Imagine a ‘friend’ who could recommend websites you’re interested in. Sound good? StumbleUpon could be the friend you’re looking for – and might just help you drive traffic to your website or blog while you’re at it.

StumbleUpon isn’t a search engine; it’s a web browser plugin that allows users to discover and rate web pages, photos, and videos. Once you download the plugin (don’t worry, it’s a fast download), you’ll use the StumbleUpon toolbar to “stumble” the web.
