After Google had the TiSP and the paper Gmail last year, this year they came up with Gmail Custom Time (http://mail.google.com/mail/help/customtime/index.html), where you'd set the time of the email you send. This sounds ridiculous, however pretty interesting too. Specially in the grad life, when our lives totally run on deadlines, if only there was a way to turn the clock back :) . I felt it was a hoax, and it indeed is.
(Not so...) Good work, Google!
