Well, I usually listen to the show on Podcast, so I'd probably just re-subscribe to the Leonard Lopate show, and continue to listen to AST Radio and The Sound of Young America, and listen to the Stereolaffs releases, and maybe the archives sometimes, and generally be just a little bit sadder. It's my students who'll suffer the most, though; I was always in a great mood when I listened to TBSOWFMU on my way in.
I was also planning on sticking a toe into the water and listen to it streaming, so I could call in. My wife has class Tuesday nights this fall so I'd be home alone. If Tom quits (and the Kid should do whatever he's gotta do), I'd obviously have to scrap that plan.
