Most blogs are personal in nature and create a fictictous (sp?) environment/atmosphere, a self whoring ground so to speak, where people link with one another, friends or otherwise, where they can brag about each other's "interesting" lives. So much drama involved.
It's a forum for elevating one's own image and stature, real or otherwise. Kind of like some here who care about their various "lifer/senior" statuses, post counts, or online reputation.
Some post way too much information and is a resourceful medium for pedophiles and/or stalkers.
Some people give too much thought into what others (strangers) think about themselves.
