"StumbleUpon is a great fit within our goal of pioneering new communities based on commerce and sustained by trust," said, Michael Buhr, senior director, eBay. "StumbleUpon's downloadable toolbar provides an engaging and unique experience to its users, but it is the similarities in our approaches to the concept of community that make it such a compelling addition to eBay."

Although you can imagine "StumbleUpon Shopping" coming soon, eBay is leaving the company alone and taking a wait-and-see approach. The corporation will remain completely intact, except for the addition of eBay's Michael Buhr, who will serve as general manager for the product.
