Are you a Stumbler? I must admit, I find myself neglecting family and friends for my nightly StumbleUpon fix.

For those of you scratching your head, StumbleUpon is–according to Wikipedia – a web browser plugin that allows its users to discover and rate webpages, photos, videos, and news articles. These webpages are typically presented when the user—known within the community as a Stumbler—clicks the “Stumble!” button on the browser’s toolbar. StumbleUpon chooses which new webpage to display based on the user’s ratings of previous pages, ratings by his/her friends, and by the ratings of users with similar interests. i.e. it is a recommendation system which uses peer and social networking principles.

And, for B2B Marketers, a StumbleUpon addiction could actually be a good one. Here are a few cool articles and tools I’ve found while Stumbling:

• KnowThis
• IA
• Internet Marketing Simple

And, a few of the more fun finds:

• Shipment of Fail
• Clean the Screen

Now for the really good part. Turns out Marketers can pay to have their sites featured or served up to Stumblers. It’s called Stumble Upon Advertising and it’s really powerful, especially if you have the type of product or service that seems to be most popular with the StumbleUpon crowd. For pennies per view, you can target an audience with your website or blog. StumbleUpon then brings users directly to the page you specify and they rate your site. It’s a great way to drive web traffic and leads.
