Podcasts!

I know I'm probably, no make that definitely, the last person on earth to discover podcasts. I don't mean that I discovered them, I've known they exist for quite some time, but I mean that I really come to realize how great and awesome they are. 

All of a sudden it's become clear to me what to do with all those spare minutes I have, for example walking to and from campus, dmv lines, any lines for that matter. The other great thing about them is that they are audio. I know that sounds dumb, we've had radio and ipods forever. But I've really lost the urge to read anything. I think grad school does that to some people... I just cannot for the life of me muster up the energy to pick up a magazine or a news paper or a book for that matter, and I only read the highlights on google news. Pathetic right?! But now... a whole new medium has opened up for me!

I'm now in some kind of podcast frenzy where I'm subscribing to new ones every day, there's just so much out there! Today I listened to an arabic class on my way to campus and the economist on my way home. Tomorrow I'm thinking NPR's Science Friday.

Any tips? What am I missing in my podcast subscriptions, what are the must-haves?
