Maybe the big change coming for StumbleUpon last month wasn’t a change in ownership after all. While rumors of eBay’s planned sale of the website-discovery toolbar have yet to be confirmed, StumbleUpon has come out with a few big changes this week.
Originally designed as a toolbar that delivers recommended pages in your specified areas of interest, StumbleUpon has seen great popularity. It even had a decent revenue model: selling some of those pageviews for a nickel a pop. ClickZ reports that one out of every 20 to 30 pages stumbled is a paid inclusion. But the toolbar may soon be a thing of the past for all users.
