In the next couple of years dead will become an important aspect of the social networks. A time will come that most profiles on Facebook will belong to people who’ll never be able to post another update. Currently due to inactivity most dead profiles will be deleted or become inactive, but I think dead will take a much more important role on the internet.
My parents and even grandparents have a Facebook account now, but in twenty or thirty years, some people I’m connected to won’t be alive anymore. It would be great to be able to browse the lives of people who are no longer around us. I’d love to read about my deceased grandmother for example, just to see how she lived her life. So instead of deleting inactive accounts, death should become more accepted and a part of our social web as well.
