I really wish that CNN offered Anderson Cooper 360 and MSNB offered the full Countdown with Keith Olbermann instead of the highlights show the put up, but I guess you can't have everything. I also listen to Slate Explainer, the NYT Ethicist, The Onion Radio News, and the NBC Nightly News vodcast, as well as one or two other things I can't remember because they aren't on the ipod right now.

I dropped that Alan Watts one pretty fast. I like and respect the guy, but his delivery was of the snooze.

Dear lord how do you guys possibly listen to all that? I mean, I'd like to, but - no.

I just went and looked up the PRI show Afropop Worldwide (which I love but haven't heard in 5 years - and it does podcast!) and discovered that the host's name is Georges Collinet. I had been envisioning "Josh Geline" (he has a strong accent.)

I listen to them mostly on my walk to work and anytime I'm travelling on buses. Some definitely get listened to more than others. The daily ones I cull fairly regualrly.

I generally listen to a few going to and from work and catch up on longer ones over the weekend if there's time. Some I just delete if they've gone overripe.

I should say that I hear about a lot of bands I end up liking from the two KEXP podcasts. KEXP also went above and beyond for SXSW, adding 10 30-min. live performances in 3 days, including the Stooges, Okkervil River, Beirut, and the Apples in Stereo.

Excellent! I've been looking to add stuff to listen to on my walks. For the moment, I only subscribe to:

Learn French by Podcast
Easy French Poetry Podcast
Grammar Girl's Quick and Dirty Tips for Better Writing
Old Time Radio Suspense
Out of the Past: Investigating Film Noir
This American Life
Watching the Directors

ETA: Grrr, line breaks again!

I dropped that Alan Watts one pretty fast. I like and respect the guy, but his delivery was of the snooze.

Good to know; I might drop it after I give it a try, because I've heard good things about the guy but if I zone out while listening, what's the point?

What's this one?

flea, I listen to them on the bus/walk to and from work, and on my lunch break.

how funny! that just came up on metafilter today, and I made a note to subscribe to it when I got home.

I also like the shorter ones, because if I'm just walking to the store or something they're a quick burst of intelligence for the ambulation.

I keep seeing oblique references about the RIAA, and people figuratively stuffing their music under their mattresses. I'm guessing this is due to the RIAA going after university students for filesharing?
