CHAPEL HILL, N.C. — If you send an email to Paul Jones, you won’t hear back from the University of North Carolina-Chapel Hill professor. You will, however, receive an automated reply that could only have come from him.
"Good Bye Email, I’m divesting," reads the subject line. The message says that Jones gave up email on June 1, 2011, and goes on to suggest more than a dozen ways to contact him: through Facebook, Twitter, Google +, Gtalk, AIM, Skype, LinkedIn, even YouTube.
