Will Tribune sell the Times? Why is NBC Universal revamping its operations? How are you supposed to know if the housing market is in freefall? Those and other tasty matters will be up for discussion Tuesday night as I jaw with KNX's Frank Mottek on business news and business reporting. The forum is sponsored by the Los Angeles chapter of the Society of Professional Journalists.
