According to Statcounter, StumbleUpon is now responsible for 43% of all major social media site (StumbleUpon, Facebook, Twitter, Reddit, YouTube, Myspace and Digg) traffic on the 15 billion pageviews that the analytics service tracks. Facebook is at 38%.
When a company with 13 million users is outpacing one with 500 million on one specific metric, additional context is needed to understand exactly what is going on.
I spoke with Camp earlier today about what exactly this recent news means for the company and why StumbleUpon seems to be killing it since August, clocking in about 1.9 million unique visitors in November according to Comscore. The site has served up over 700 million "Stumbles" (referral pageviews to other websites) in December 2010 compared to 400 million Stumbles in December of 2009, according to internal analytics.
