Just reading another thread with a 'serious' discussion and I realized that they all seems to be such a waste of time.
People with strong beliefs on either side will furiously type out impassioned posts, full of whatever data they can grab to support their claims. The people on the other side will do the same.
Things will go back and forth until people lose interest or it degenerates into a shouting match.
And no one changes their position. They'll believe what they want to believe, and no amount of data, clever words, or passion from the opposing point of view will change their minds. That can't be done on a discussion board.
So it all seems like mental masturbation. A near total waste of time that accomplishes nothing.
Maybe this is why there are so many posts about chuck norris and pie.
