A few years ago, I went on a kick of enfriending basically everyone that I knew from my home town in Alaska and I ended up with one friend who was one of the little kids in my church growing up. Of course, he grew up and was apparently gay and had issues with depression.
Sometime earlier this year, he ended up committing suicide.
That means that now I have a dead friend. Since Facebook doesn't seem to have a policy of purging its users of the dead or just people who don't use Facebook often, it looks like his profile will just continue on espousing "long live the flying spaghetti monster" as a religious view.
On one hand, it's kind of odd that the page will probably last for as long as facebook does. (What is the lifetime of a social networking site anyway?) On the other hand, it's a little bit comforting that the web will remember you even if the rest of the world doesn't.
