what topics are you interested in?

Greg Proops Worlds Smartest Man is brilliant. More impressive still when you have been listening to them each week over 6 months. He is a bright and funny man.

The Bugle (assuming it is continuing) is great.

The Moth is often very good.

From the BBC, Danny Baker, Fighting Talk and Desert Island Discs do it for me.

so judicious use of the 'Search' box might yield some good results.

Still, for what it's worth, here's my recommendations

In Our Time
Material World
NPR Car Talk
Adam and Joe on 6 Music
Danny Baker's Radio 5 show
Radio 4 Great Lives
Radio 4 Documentary Of The Week

Q from CBC has had a cracking array of guests recently, including PJ O Rourke, Tom Waits, Gilian Welch, Ryan Adams, Elbow, David Cronenberg & Demetri Martin.

99% Invisible is about architecture and design and is fairly short, but interesting.

LA Review of Books has an interview with music critic Simon Reynolds.

On Being has an interesting interview with Roseanne Cash.

Both The AV Club's Reasonable Discussions and APM's Dinner Party have changed recently. Reasonable Discussions has moved to a bi-weekly with a longer discussion of the arts in general and Dinner Party is now an hour long, with no real loss in quality.

I thought a similar query had been posted before. I shall have a look at the links.

Since the last query, there are likely to have been some new podcasts which have started up (and some that have finished - e.g., Collings and Herrin podcast).

Speaking of Herrin(g) - his daily blog "Warming Up" is now available as a podcast. The blog is often very funny as well as being an insight into the working life of a comedian who has had/is having some success but isn't at the stadia-filling levels of M. McIntyre or P. Kay (Peter, not Phil).

Turning to Sport... it seems to be filed under comedy, but this is the best podcast out there involving a middle-aged man playing himself at snooker whilst also commentating and refereeing. It's "Me1 vs Me2" snooker. Unlike professional snooker players, who have it easy, this is the podcast of Richard Herring playing himself at snooker in his spare room with the added challenges of (i) ironing board, space hopper, old sofa and piles of unsold copies of "Bye Bye Balham" hampering his play, (ii) poor chalk which doesn't actually go onto the tip of the cue, (iii) not really knowing the rules of snooker and (iv) not really being able to play snooker.

A must for all sports fans*.
