We're living in the bubble again. CNN's little experiment with opening up one daily hour of its day to the very different coverage of its international channel, titled "Your World Today," seems to have been yet another victim of Hurricane Katrina. On the heels of the entirely understandable pre-emption of the program during the height of the disaster, it has failed to return to the schedule, and no announcement of its cancellation has surfaced, at least to the eyes of this Googler. Maybe the comparison of the measured, reasonable, non-frantic output of CNNI with what the domestic side grinds out these days was just too painful. Or embarrassing.
