New report from the Pew Internet and American Life folks. Turns out that social Internet users are social in meatspace as well.
“75% of all American adults are active in some kind of voluntary group or organization and internet users are more likely than others to be active: 80% of internet users participate in groups, compared with 56% of non-internet users. And social media users are even more likely to be active: 82% of social network users and 85% of Twitter users are group participants.”
