I just happen to think seriously that what will happen when people die and leave all their blog behind. Should they kept all the passwords in one place so there children can take care of it and pass on through generations, like property? Or the blog should die with person and became something like a memorial to the person. And what will happen if he/she were die all of in sudden and have no chance to even share those usernames and passwords to the others? Those blogs will remain freeze forever.
I read about one Facebook user that had died recently and the web engine still suggested him to be a friend to you. Imagine you hit his page and found out that he is dead. That might sound a little creepy. There should someone come up with a prep scenarios and procedures for a blogger ready for his/her death. So I could be prepared mine.
