A startup called Perpetu wants to make it easier for us to ensure that our social network accounts are unplugged once we shuffle off this mortal coil. The service, which currently lets users add Facebook or Twitter accounts for free, just launched its premium service, which costs $15 a year or a $100 one-time payment and includes support for LinkedIn, Gmail, Dropbox, Flickr and GitHub.
