The official Graphisoft blog mentioned podcasting and recommends listening to Archispeak:
The Archispeak Podcast is one podcast I’d recommend checking out. The trio of hosts; Evan Troxel, Neal Pann, and Cormac Phalen get together regularly to have casual conversations about all things architecture. What I like about their style is they celebrate the triumphs and highlight successes AND are unafraid to point out failures or situations where they think the proverbial bar was missed.
