Kind of seems like Jocasta is on the show just to help get the demographics. Black women typically don't bring much to the show, and I think it's because Big Brother gets the quite, reserved ones. They need to go to South side Chicago and find a complete thug black woman who doesn't give two ***** what someone says and is constantly on the verge of being expelled from the Big Brother house.
Same with the "feminist"/tough female. they bring nothing and this is the person Big Brother should stop going after. Joey, GinaMarie, Jenn and Jojo have done nothing productive. GM and Jenn lasted pretty long in the game, but neither did anything productive in the house. One let Frankie and Shane fight each week to eliminate each other, and the entire house new if they were in the final 2 vs. GM, they would win, so they kept her.
