Fred Wilson posted a blog post based on an analysis of Comscore stats, looking at US vs Rest Of World traffic for some of the largest web properties.
In February 2010, 84% of Google visitors, 78% of Facebook visitors and 72% of Twitter users were from outside of the US.*
*Wilson used Comscore’s “Rest Of World” phrase, which set off quite a lively debate in the comments to the post – worth a read for anyone interested in the semantics of global communities. Wilson’s points about monetization opportunities are also worth some time.
