In your final moments, updating your Facebook status or sending a Tweet should be the last thing on your mind. A morbid new service promises to take care of that for you.

Messages can be released either all at once or on a predetermined schedule -- meaning your words can go on, and on, and on ... online that is.

"If I Die" is a free Facebook app and it gives people a chance to write their messages or record their videos well before the end arrives. Upon death, three friends that you assign must verify your death, at which point your updates will be released to the public.
