800 Million: That’s a Lot of Stumbling

Users of StumbleUpon are now up to giving the company 800 million “stumbles” a month, reports Business Insider.

The company’s algorithm tracks what its users like and pushes them toward similar content. For StumbleUpon, this translates into income via ad placement among the stumbles.

Business Insider points out the “great entrepreneurial story” of StumbleUpon: eBay bought the company from its founders in 2007, according to Wikipedia, only to sell it back to the founders two years later. StumbleUpon has since remained independent and supported by investors.
