TRENDING:STUMBLEUPON'S TRAFFIC GROWS RAPIDLY TO MORE THAN 50%

Which social media site drives the most traffic to the rest of the web? If you think it's Facebook or Twitter, you're definitely wrong. 

StatCounter new data shows that StumbleUpon is the most dominant source of traffic among the world's top social media sites. For the first 18 days of August, StumbleUpon accounted for 50.27% of all referral traffic from the top 10 social sites. The second is Facebook with a 38.9% market share, while Reddit, YouTube and Twitter each garnered less than 4%.

Yes, to say the least, the stats are surprising. Few days ago, I posted an Article that StumbleUpon surpassed 25 billion clicks of its StumbleUpon button and the traffic of this site has been growing rapidly. StumbleUpon has nowhere near as many users as Facebook or Twitter but it does track approximately 3 million websites which is a very decent sample size. 

Of course, StumbleUpon's traffic of 12 million could not beat the 750 million of Facebook but its service clearly grows by influence to drive more traffic.
