Stuart Crainer: Over the last year we have enjoyed capturing some great ideas and colourful characters in our Thinkers50 podcasts. It appears that the Thinkers50 community also enjoys them. We speedily passed 10,000 downloads and are now heading ever upwards. The best podcasts — and the most popular — are the longer more conversational ones where we explore the ideas behind the thinker and, indeed, the thinker behind the idea. We look forward to more ideas hunting and insight-laden conversations this year. In the meantime, we celebrate the pick of our 2016 podcasts.
