Lately I've been listening to CBC Radio's new show Spark.
Some of you may recall that I'm not always fond of the CBC, but they've got something good going with Spark. It's the sort of show that would appeal to demographics that might otherwise view the CBC as stodgy and uninteresting. Spark's host, Nora Young, discusses the latest technology and technological phenomena with guests. Specifically, the show focuses on how technology integrates into and impacts our daily life. So even if you aren't a technowizard, you could still find the show interesting (and perhaps even informative).
Take a look at the Spark blog to get an idea of what sort of topics the show's covered in the past. Even if you don't get CBC radio where you live, you can listen to Spark via podcast--that's how I listen, because then I can just put it on when it's convenient.
