Nobody really would care for now, but I'm sure people would catch on after a while. You could post recent pictures of places you went and shit--not just to log like "Hey, this is what I look like. Kay. Now you guys now. I'm leaving this thread forever now."

It could become a sort of mass-photo-blogging thread.
