Just had a terrific afternoon visit to XM satellite radio’s headquarters in Washington DC, to visit the production facilities for their POTUS ’08 channel. It was a pleasure to finally meet Joe Mathieu in person after exchanging weekly emails and phone calls regarding PJM Political, and to also meet his fellow on-air talent, Rebecca Roberts and Tim Farley. (Not to mention spending a few minutes on the air discussing Pajamas and its origins in between the big story of the day.) XM has quite a production facility–on the other hand, in a way, it’s also a slightly more compact than you might imagine. Just as today’s technology allows individual blogs to punch far above their weight, it also allows a single facility in DC to pump over a hundred channels of audio out into the hinterlands via satellite.
