One of the best radio shows in existence finally is available on podcast. Eaqch Ideas episode explores a question or topic from many different perspectives, usually interviewing major figures in the relevant fields. If (like the other reviewers) I had to compare to other podcasts, it's very similar in style and in subject matter, to WNYC's RadioLab. Ideas was a weekday evening highlight when I lived in Canada. Having some of the best shows available on podcast is like having that really intelligent, thoughtful, funny friend who you dearly miss since they moved away a few years ago, move back to town, and finding them even more enjoyable company than before!!
