Remember in the Blair Witch Project when the cameraman said that filming stuff made it easier to bear? That is, keeping things at an arm's length and treating them as subjects to be filmed, with yourself as the cameraman, helps remove you from the fact that you are actually living. It seems pathetic at first, but also it's kind of serene - it can give you some perspective and it can keep you grounded. (They sort of used the same idea in Cloverfield, too)
I bring it up because there was an article in the Express today how fashion model Kimora Lee Simmons Twittered during her labor. It makes me wonder if this sort of thing won't be more common - people Twittering not to reach an audience at all, but just to reach themselves.
