I have a post on Join the free Diaspora and build YOUR mindfile on the Space Collective website Some excerpts:
Eventually, Diaspora may become a social web: a large decentralized network of pods operated by different individual and groups, linked by common protocols, and able to deliver all the things (friends, status updates, chat, groups, pictures, video, like, unlike, share...) that we have in Facebook and many more.
Once you are connected to users on other pods, you see their activity in almost real time like if they were on the same pod. If the Diaspora network takes off and achieves critical mass, it will be an open, decentralized, distributed P2P social web.
Billions of digital natives born in the 00s will have deep and detailed records of their lives, thoughts, feelings and personalities, on future social networks. According to the Bainbridge-Rothblatt hypotesis which seems more and more plausible in light of recent scientific advances, sufficiently advanced future technologies may be able to ignite these "mindfiles" and bring them back to life.
