Lifepath.me presents a completely different world view than facebook timeline. FB reminds you of your past shiny happy moments you cared to capture with a camera. Lifepath in its current form is almost a reminder of your biological limitations and that every single day counts. It caters for much smaller audience than FB, because people in general do not wish to be reminded about their death. With the lack of pictures I can see it could become a sort of anti-facebook private diary of achievements that really mattered. I too think that Diaspora with their idealistic vision of social networks would be an ideal buyer here. They could also use some design lessons from this app, they badly need it.
