The morning mail is my enemy
Herein lies a problem with communication. Someone takes the time to write you. Social conventions obligate you to respond (though you'd be better off if you didn't respond to most). Even if you choose to "put it off for later," it weighs in the back of your mind.<p>Now fast forward to modern day, and the cost/time required to send an email is trivial. More emails get sent. Busy people get more inbound. Social conventions obligate you to respond, especially if it's someone you know.<p>We'd all be better off if the expectations of response were lower. That's why I like Twitter. There is little expectation or obligation to respond.
