I find this fascinating, if a little uncomfortable to think about:
"In a recent poll only 20% of UK adults admitted to having given though to what will happen to their social profiles after they die. Of this group there was quite a divide in how they would want their profiles to be maintained after they have died. Almost half (43%) of those polled said that they would want their social profiles closed down, while 20% said that they would want their profiles still active but simply closed for comments. One fifth were unsure as to what they would prefer and 16% would like their profiles to remain online with commenting enabled forever. Have you considered what your preference would be?"
