Um, great news! For those of us who are extremely aware and accepting of the fact that we will all, one day, die, strong>Facebook /strong> is now offering an app that lets its more forward-thinking users write a bunch of posts, messages, etc. to be published after they have died. Obviously, there are truly sentimental and heartwrenching reasons to do this, and then there are, of course, the people who want their friends to suffer through an extremely macabre prank. BOO!
