Recently, Jon Antilles reposted a masterlist which had a link to a post by Colin Wright. Digging around, I fond that Colin hosts a podcast, Let's Know Things, which aims to give contextual information on a wide range of subjects (including tech, politics and sociology) and integrates them into a high level view of how they fit in the world.
The episodes are not particularly in depth, being about 45 to 90 minutes long but they do give a good jumping off point for folk wanting to research them further. Or just gently drift off to sleep to Colin's gravelly voice (dangerous when on night shift).
