It's not my go-to place for learning interesting things, though, especially when there are shades of grey - or possibly ideas that aren't necessarily popular with either conservatives or (social) liberals. For me, that has to be the RSA, where some of the most interesting thinkers in the world come to put forward (admittedly usually along with a book) ideas that I'd either previously not considered or had wildly different views.
Another excellent source of thoughtful material are some of the science-y podcasts from Australia's ABC. In particular Future Tense and the Science Show go into depth and background for subjects that are all to often glossed over in the pursuit of a catchy headline or political opinion.
And that's the point: the interesting thing here is that in most cases, these are presentations by experts, not pundits. In an era where pretty much anyone can get their "point of view" on some kind of media
So - do yourself a favour, and get some of these podcasts (or watch the videos or read the transcripts) and be better informed as well as entertained. I virtually never listen to the radio live these days.
