One day, you're going to die. And when you do, you online presence—like your social network profiles, your blog comments, and your web services—will serve as your very first memorial. Here's how it'll play out.

More than any other service, Facebook will be the most important fixture in your digital mausoleum. I mean, it's a basically a catch-all for your memories, with timestamped comments, loads of personal info, and pictures. (Oh dear god, the pictures...) It's the first place acquaintances look after someone dies, and the first place the press will look if your death was particularly public or tragic.

And Facebook knows this. They've got a healthy help section for the bereaved, which lays out what how one can deal with a dead profile.

Facebook knows you are going to die someday. As depressing as it may sound, there's a form you can fill out for this.
