Having a little bit of buyer’s remorse there, eBay? According to TechCrunch, eBay may be looking to sell off StumbleUpon after acquiring the company a mere 18 months ago for $75 million. An anonymous source claims that eBay has hired Deutsche bank to help them find the right buyer. No asking price has been mentioned but eBay may take a loss as StumbleUpon’s popularity (based upon traffic data) has been steadily declining. It appears as if eBay may be streamlining and finally selling off some of these superfluous acquisitions that contributed little, if any, to their core auction and classified services. A little hint to the prospective buyer: if you really want to help boost StumbleUpon, get rid of that annoying toolbar and focus on delivering the content through your website instead.
