Rahel Bailie at Intentional Design just told me about the podcast series, the Userability Show. In each podcast, Robert Hoekman and Jared Spool use their wit, humour, and knowledge to answer questions from practitioners.
The podcasts are great for listening to while you work. Subscribe to the Userability podcasts by using iTunes, or find the link on the User Interface Engineering‘s site and play it manually.
Enjoy!
