I've been a Krulwich fan forever (man do I miss the old Nightline!) and always listen to new Radiolab releases, but the show does walk the line of being too self-satisfied and overproduced. It's so heavily edited they can't maintain a schedule. I'd rather they drop ten percent of the polish and get out fifty percent more content. A good trade. A Life Well Wasted, explicitly modeled on RadioLab but attempted with fewer resources, fatally cratered for the same reasons.

My favorite Radiolab release was #15 in their shorts sub-series. Jeffrey Tambor reading David Eagleman's short "Sum". (http://www.radiolab.org/blogs/.....13/15-sum/) Great content given great reading. A must.

Been toying with the idea of asking FFC folk for their favorite podcasts. May as well do so here and plop in my list here. I subscribe to 100+ but won't list all. Many are radio shows repurposed (like 'Lab). Old episodes of BBC ones won't be available for those living outside BBCLand. The real loss there is History of the World in 100 Objects which recently wrapped.

Americana: inside the USA (BBC4)

APM: American RadioWorks (documentaries)

Backstory With The American History Guys

Bell's in the Batfry (not a big fan but hoping to find the voice of an FFC overlord in it :D)

Bob Edwards Weekend (ex-NPR host's satellite radio show)

A Brief History of Mathematics (BBC4)

Comedy Death-Ray Radio

Coverville: The Cover Music Podcast

Creative Screenwriting Magazine

Filmspotting (new to me; still undecided if it's a keeper)

Gamers With Jobs

Geeks Versus Nerds (far funnier than it should be)

Gourmet's Diary of a Foodie (videocast; the magazine and 'cast are dead but full archive should be available)

In Our Time With Melvyn Bragg (BBC4, liberal arts education in a box)

Irrational Behavior (on hiatus) & Irrational Interviews

Judge John Hodgman (includes the older This Day in History podcast)

KCRW's Design for the Real World

KCRW's Left, Right, and Center (US politics)

A Life Well Wasted

Little Atoms (mostly interviews with working scientists)

The Media Project (from a public radio station in NY state USA about media issues, particularly media coverage of politics)

The Nerdist (comedians interviewing other comedians; hit or miss but can be great)

NPR's On the Media

NPR's Culturetopia (specifically the Pop Culture Happy Hour, the best of which is the funniest stuff I've heard in years. Get "Schemmeys, Rediscoveries, and Unusual Justice" and skip to 22:30)

NPR's It's All Politics

NPR: Wait Wait Don't Tell Me (panel comedy quiz about week's news)

Out of the Game (maybe dead; Jeff Green and several other greats formally from game press)

Real Time with Bill Maher (audio of his HBO show w/extra content)

Savage Love (Sex & relationship advice. Blunt, practical, funny, and spectacularly not safe for work)

All the Slate.com audio podcasts, including the sports one and I'm no sports guy

The Sporkful

Studio 360 with Kurt Andersen (if you take only one from the list, this is it!)

Stuff You Missed in History Class (the sourcing and accuracy can be dodgy but it's good fun)

TEDTalks audio and video casts. Slightly different coverage of TED conferences.

Three Moves Ahead (strategy with a heavy PC bias; my favorite extant game podcast. early episodes often featured Chick & Bruce)

Too Beautiful to Live (what if drivetime FM radio shows didn't suck? you'd get this!)

WTF with Marc Maron (if you can survive or skip the half of each episode where Maron uses you as his therapist, the interviews with every comedian you can imagine are fantastic)

I also skim the 60 Minutes and Meet the Press audio rebroadcasts.

Now, your lists! [Image Can Not Be Found]

I didn't think I'd enjoy Lost.  Boy, was I wrong.
