Who would have thought 15-20 years ago that e-mail would turn out to be a hindrance to productivity, not a booster. Perhaps it's that e-mail is too easy to send so people do it even when it wouldn't be necessary or there would be a smarter way to communicate. So many people end up with thousands of e-mails a day, only a few of which are important. It's hard to assess the overall effects of e-mail vs. productivity, though.
