I've recently discovered, and been listening to, a podcast series called - Insert Content Here. It's produced by a company specialising in Drupal CMS development (Lullabot) but the majority of features are tech-agnostic; instead focusing on content management strategy.
The most recent episode I listened to was great - a conversation between the host Jeff Eaton and my favourite writer/speaker on content strategy, Karen McGrane. Titled '2013, a year in review', the discussion moved through a series of trends and challenges in CMS design and management, and content strategy.
