Social discovery network, StumbleUpon, recently crossed the 10 million registered user mark. TechCrunch discovered this via a review posted by one of the site’s employees.
StumbleUpon has, however, chosen not to make a big hue and cry about it. An employee of the site just stumbled the profile of the new entrant and mentioned that he was their official 10 millionth user. He is a 20 year old male from Colombia, and his user name is Nellzom.
In April 2008 StumbleUpon had registered 5 million users and they have doubled that number in the last two years. In fact, the StumbleUpon blog announced that they had 9,908,350 users just over a fortnight ago, which means they signed up approximately 6,500 new users each day in the past 2 weeks.
Statistics released by the company show that they have seen an 118% growth in the number of active users since 2009 and have delivered 5.4 billion recommendations since April 2009, half a billion of which were in March 2010.
StumbleUpon was acquired by eBay in 2007 for $75 million but separated from eBay in the last year. The company is now faring pretty well in its recently re-acquired start-up status.
According to reports published last month, StumbleUpon drove more traffic to third-party websites than many of the other more popular sites such as Twitter, Reddit and Digg.
An average StumbleUpon user stumbles about 25 times a day. Users of the StumbleUpon add-on for Firefox stumble sites about 400 times a month.
The growing popularity of StumbleUpon can probably be attributed to the fact that it is very easy to operate. Users can discover new sites with just one click and also rate them with a simple thumbs up or a thumbs down with just one more click.
