Buffalo's far from the second biggest cluster for Cumulus. Thanks to the Citadel take-over, they now have NY, LA, Chicago, Dallas, San Franciso, and a whole lot more. See http://www.citadelbroadcasting.com/

Meanwhile, the Cumulus website STILL hasn't been updated to include the former Citadel properties. I guess that tells us all we need to know about their commitment to the digital platform.
