Those of us older than 25 can’t imagine a life without e-mail. For the Facebook generation, it’s hard to imagine a life of only e-mail, much less a life before it. I can still remember the proud moment in 1996 when I sent my first e-mail from the college computer lab. It felt like sending a postcard from the future. I was getting a glimpse of how the Internet would change everything—nothing could be faster and easier than e-mail.
