" Here we are, practitioners of memos:     We send e-mail and we receive it,     We copy it and forward it and save it and delete it.     We write to move the data, and                 organize the program,                 and keep people informed—     and know and control and manage.   We write and receive one-dimensional memos,         that are, at best, clear and unambiguous.     And then—in breathtaking ways—you summon us to song. "
