This reminds me of Storyworth, a site to "record family stories." After signing up, you enter your mom or dad's email and it send a question for them to answer each week like, "What was your first car?" or "How did you meet your spouse?"
It's rarely discussed but lots of people still write diaries or some version of it. My ex-girlfriend used to record what she did that day and who she spent her time with in Google Calendar.
Just saw this tweet from @dhg (designer at Medium):
"A peek at the start screen of a passive journaling app I've been working on: http://dribbble.com/shots/133521..."
Looks beautiful. Curious if there's overlap with OhLife.
