comScore says that in August 2011, more than 72.2 million people used their mobile device to access a social networking site or blog. That’s up 37% from the previous year.
More than half of the mobile social networkers tapped those sites daily and 38.5 million people used a social network app to do it.
Facebook, Twitter and LinkedIn, all showed a marked increase in mobile access over the last year. Facebook still rules for pure numbers of people, but Twitter showed the largest growth. And look at little LinkedIn jumping up 69%.
