Via Marginal Revolution. For some, voice mail is losing its allure.
Well for me, I hate talking to machines. Nowadays there are so many communication devices to choose from, and if it is not an emergency, people would probably send an email or leave a text message instead. But when they think the case is important enough to be made through a phone call, a machine instead of a person answering is probably not very pleasant to most. Personally I would rather people see the missed call from me, and call me back in person (if they think I am worthy for them to do so).
