Colleges and offices seem to be getting rid of them. When I tour office space with clients and review plans one items I never see is a mail room with mailboxes in it. Rest assured we still get mail, but by no means is it the mainstay of communication.
According to an article in the Boston Globe “at the end of the summer, the [Bates College] boxes will click shut for the last time, a sign of how the Internet is changing college campuses.”
