Yeah, I'm not sure either. It's an odd trend that seems to be growing around here lately, and even starting to take on an air of pretentiousness ("illiterates need not apply"..?). If you're going to start holding it against people for not wanting to read your life story posted on a message board then well, good luck with that.
I used to be the biggest offender of this however, well maybe second to Anthony1. Shit, there was goatdan too... I'll take third. Of course, my near page-length essays were usually relegated to Off-Topic. I've since decided that doing that is a bad idea on a message board, and now try to refrain from it. Brevity encourages discussion. Even this feels like too much, so I'll just cut it short here and end with a quote from a movie I saw a few days ago.
"Wake me up when we get to the birth of Christ."
