'Fringe' picked up for 4th season

Rejoice, Fringiacs, rejoice: One of the best shows on television (period) just got a fourth season. Yes (Fringiacs), it was touch and go in this universe, with low ratings on Fridays but astronomical time-shift ones. J.H. Wyman, one of "Fringe's" two showrunners (Jeff Pinkner, the other) said in a tweet last night that "Fringe was picked up . . . thanks 'Fringedom.'" As readers may know, I've been concerned about "Fringe's" fate  but clearly Fox was not. This is for a full season order.
