I think that's the point -- a passive journal/log of your life and connections (I default all posts to be "Only Me" and share what I want as appropriate to further cement in my mind this idea of a personal journal that's backed up in the cloud.)

It's in this perspective that I don't think you're asking the right questions -- would you consistently read and curate old journals or photo albums? You may every now and then, but the point is that they're there for later reflection...
