StumbleUpon – The Quiet Achiever?
By Anna Johnson on February 10th, 2009Amit Chowdry reports that social bookmarking site, StumbleUpon now has 7 million registered users. ReadWriteWeb says this number makes Stumbleupon about 50 percent more popular than Twitter.
StumbleUpon, which was bought by eBay in May 2007 for $75 million, involves installing a toolbar and then giving webpages you visit a ‘thumbs up’ or ‘thumbs down.’
Over time, StumbleUpon works out what kind of websites you seem to like and will direct you to other, similar sites, based on this.
