The sort of grief displayed over Peaches' tragic death is nothing new.
"Diana was probably the first to inspire that type of collective grief," says psychotherapist and bereavement counsellor Irene Deering, of Mind and Body Works Counselling and Psychotherapy Centre.
"Her death allowed people to grieve for whatever was going on in their own lives, and I think there's a similar thing happening with Peaches. Here was a girl whose own mother died in tragic circumstances, who had gone through her wild years, and just when she finally seemed to get it together, suddenly she's gone.
"I have a daughter the same age as Peaches, and her immediate reaction was: 'This is awful'," adds Deering.
"Young people that age look for role models, so when someone like Peaches dies, they feel a genuine need to say something about it, even if it's just 'that's so sad'. It's a gut reaction." According to communications consultant Damien Mulley, of Mulley Communications: "For some people, somebody like Peaches Geldof dying so young will resonate because of their own circumstances. There's also a sense that people feel they need to be part of the group by tweeting or sharing on Facebook their memories of this girl that they've never interacted with.
"You do wonder do some people just write on their [Facebook] wall to be seen to be sharing their condolences.
"It's a bit like going to the funeral of somebody you've never met where you shake hands with the family and say 'Sorry for your loss'," adds Mulley.
"You may never have met the person, but you're doing it because that's the thing to do.
"To a degree, we've got that social obligation now with social media'.'
