StumbleUpon combines website recommendations based on user input via ‘Thumbs up’ and ‘Thumbs down’ votes with a social review site with search features. It also features a browser plug-in that lets you ‘channel surf’ the web by redirecting you to a random website – that has been previously voted by other users – based on your interests. The service currently has a growing user base of 2.3 million users.
eBay's plans for StumbleUpon – or even if the deal takes place – is yet to be seen. However, SumbleUpon’s features could improve community aspects of the auction site and make interesting auctions easier to find.
