The rise of social media

Interesting findings from some Nielsen research about how Americans spend their time online.  Nearly 3 times as much time is spent on social networks as on email - a huge jump from a year ago.  I would like to see this data compared the volume of emails sent as my inbox seems to be as busy as it was last year.  I guess we are just paying less attention to what comes in which can only be bad news for the spammers.
