Firing Chalian will not change Yahoo’s bias one bit. It is and will remain a far, far left website that will continue to promote all things liberal and bash conservatives. Nothing will change from this minor personnel change. And Chalian will quickly be picked up by another left wing outlet (e.g., MSNBC).
Fired because he got caught.
