TechCrunch is reporting that Social networking and bookmarking site StumbleUpon.com is for sale by eBay which bought it only about a year ago for 75 million.    It’s not clear how much they want for the site but due to stagnant growth in traffic and the ongoing challenges to social network monetization, it would seem likely that eBay would be happy to get little more or even less than 75 million to unload a site that does not really match up well with eBay’s core values and experiences which are “selling stuff by auction”.

Interestingly eBay already has one of the world’s largest social communities in the form of buyers and sellers who interact in a huge way on a grand scale every day, although I don’t think eBay has made a concerted attempt to extract additional value or community from those buyer and seller relationships.
